Definitions
- the invention relates to an assaying system. More particularly, the invention relates to a machine readable assaying system for analyzing a specimen of physiological fluid to detect the presence or absence of particular substances therein.
- the machine readable assaying system contemplates the utilization of machine readable bar-code patterns imprinted upon a test card which change form in response to a physical, chemical or biological reaction.
- the test result which is encoded within the bar-code indicia imprinted upon the test card is read by an appropriate decoding apparatus (i.e. a bar-code reader/scanner), and the decoded results are stored in a memory unit and transmitted, if desired, to a distinct location.
- a test administrator merely scans the bar-code. Because the bar-code patterns change form in such a subtle yet varied manner, the administrator or another observer of the test card is unable to discern the results. Accordingly, the privacy interests of the donor are preserved, as well as human interpretation errors, transcription and translation errors.
- the status of an individual as a drug user or abuser is determined by analysis of the individual's physiological fluids, namely urine.
- a specimen of urine is collected, and a highly sensitive screening test is first performed, usually at a centralized laboratory. If specimen samples screen positive at the central laboratory, then a more sensitive and controlled confirmation analysis must be performed.
- a machine readable format such as bar-coding
- a distinct location such as a central laboratory/processing office.
- the central laboratory/processing office could then electronically, telephonically or manually (via a delivered hard copy) communicate a responsive “negative test certificate” to the employer for those individuals testing negative (indicating that these individuals are candidates for immediate employment).
- a sample specimen of physiological fluid from only those individuals who tested positive would then be requested by the central laboratory for standard “confirmation” testing.
- FIG. 1A illustrates a diagrammatic perspective view of a test card of an on-site machine reable assaying system.
- FIG. 1B illustrates an enlarged portion of the embodiment of the test card of FIG. 1A .
- FIG. 2 is a high level functional diagram of an embodiment of an assaying system apparatus to read/interpret the test card of FIG. 1A in accordance with the invention.
- FIG. 3 provides a more detailed block diagram of an embodiment of if the apparatus of FIG. 2 .
- FIG. 4 provides another embodiment of an apparatus to read/interpret test cards of the present invention.
- FIG. 1 depicts a test card 22 of an on-site machine readable assaying system, having various indicia inscribed thereupon. More specifically, the test card 22 possesses machine readable assaying means 32 (also to be referred to hereafter as an encoded machine readable data source).
- the machine readable assaying means 32 preferably comprise in part a plurality of individual analysis strips 34 , each consisting of antibodies and/or reagents capable of chemically analyzing a sample volume of urine to detect a positive presence of a particular substance (such as marijuana, opiates, amphetamines, cocaine, PCP, etc.).
- assaying means in this particular field were configured merely to visually indicate the positive presence of particular substances.
- the plurality of individual analysis strips 34 are illustrated as an essential component of the machine readable assaying means 32 (also referred to as bar code indicia).
- each of said analysis strips 34 consists of the antibodies and/or reagents which are capable of visually indicating the positive presence of distinct illicit substances.
- the machine readable assaying means 32 may be formed, as shown in FIG. 1B , of a pattern of elements including one or more fixed strips 33 a, one or more blank regions 33 b, and the analysis strips 34 , to produce the encoded machine readable data source.
- the detection of the presence of a particular substance or drug will result in one or more of the analysis strips 34 changing from a first (light reflective) color to a second darker (light absorbent) color—or visa versa.
- the pattern of analysis strips 34 , fixed strips 33 A, and blank regions 33 B when configured to comprise the encoded machine readable data source may be provided to encode one or more characters/digits of information or other data. Accordingly, by the inclusion of the analysis strips 34 along with the plurality of fixed strips 33 a and blank regions 33 b, the detection of one or more illicit substances may cause the overall pattern of fixed 33 A and test 34 strips (bars) and blank regions 33 B (spaces) to vary, and hence the encoded information represented thereby to be altered.
- machine readable assaying means 32 comprising the encoded machine readable data source may be comprised of one or more bar code indicia whose pattern of bars and spaces (and associated coded digits) is altered in accordance to the particular substances detected via the inclusion and appearance of one or more analysis strips 34 within the bar code indicia. Accordingly, the particular pattern of bars and spaces that result from an exposure the physiological fluids of a donor, as provided by the machine readable assaying means 32 , is contemplated to produce a distinct machine readable indicia.
- one or more of the individual analysis strips 34 which comprise the bar code indicia of the machine readable assaying means 32 contain reagents or antibodies whose visual appearance is altered in response to physiological fluid, regardless of whether any illicit drugs are present within said fluid. It is further contemplated that these “control” analysis strips 34 C be situated such that their detection amongst the pattern of strips 33 A and 34 and blank regions 33 B (bars and spaces) comprising the bar code indicia does not vary the character of the information encoded therewithin. For instance, the bar code indicia of the machine readable assaying means 32 would indicate, if decoded by an appropriate device prior to contact with physiological fluid, a negative presence of illicit drugs.
- control analysis strips 34 C Upon contact with a volume of physiological fluid which lacks the presence of illicit drugs, the “control” analysis strips 34 C will appear. However, their placement amongst the standard test strips 34 , fixed test strips 33 A and blank regions 33 B will not effect the initial encoded character of the bar code indicia. Accordingly, a negative assay will be determined.
- control analysis strips 34 The function of the “control” analysis strips 34 is to prevent an administrator of the test from learning the outcome of the assay. If, subsequent to the administration of each assay, some type of change occurs to the visual appearance of the machine readable assaying means 32 , then the test administrator will be unable to discern positive test results from negative results. Only the device used to decode the encoded bar code indicia will be able to determine whether the donor's specimen of physiological fluid tests positive for illicit drugs, and if so, which particular substances were present.
- the test card 22 of FIG. 1A also possesses adulteration detection means 36 .
- Said adulteration detection means 36 are capable of determining whether a particular specimen of urine or other physiological fluid has been tampered with by administering either chemical analysis (to ensure that the chemical composition of said specimen is consistent with that of standard, non-adulterated human urine) and/or temperature analysis (to ensure that the specimen has been recently excreted from the donor and has not been brought to the test site by the donor from an earlier excretion).
- quality control indication means 38 are also present upon said test cards 22 to ensure that the reagents of the analysis strips 34 are functioning properly.
- Said quality control indication means 38 are configured to generate a signal upon contact with urine or other physiological fluids, regardless of the presence of illicit substances, to indicate that the analysis strips 34 have not been degraded due to improper storage, etc. If the quality control indication means 38 fail to generate a signal upon contact with the urine, the test card 22 should be discarded.
- an identification code 42 which may be provided as a pattern encoding items such as production batch numbers of the test card, a date of manufacture, etc. It is important to note that the identification code 42 pattern represents a machine readable (and decodeable) pattern, and as such may easily be “read” by a suitable device and received by a computer or controller means for processing, dissemination, or other appropriated actions.
- alignment aids 46 that may be provided to aid in the alignment of the test card 22 for reading or scanning by a properly arranged device. It is important to note that other arrangements of the identification code 42 , the quality control indication means 38 , the adulteration means 36 , and the assaying means 32 are possible and contemplated. For example, skilled persons will appreciate modifications such as including the quality control indication means 38 and the adulteration means 36 within the elements composing the assaying means 32 , as seen in FIG. 1B . Accordingly, quality control indication means 38 and the adulteration means 36 may determine the overall “coding” provided by said assaying means 32 .
- the quality control indication means 38 be incorporated with the “control” test strips 34 and situated such that their detection amongst the pattern of strips 33 A and 34 and blanks 33 B (bars and spaces) comprising the bar code indicia does not vary the character of the information encoded therewithin. Still other modifications are possible and contemplated.
- FIG. 2 there is provided a high level functional diagram of a test card reading apparatus 60 .
- a test card reading unit 54 is included, which is operatively coupled to a control and communication means 56 .
- the test card reading means 54 is provided to “read” and determine the particular patterns present on the test card 22 .
- the reading of the patterns of the test card 22 may result in a plurality of digits or characters being determined (or generated) by the test card reading units 54 , which may be communicated to a control and communication means 56 .
- the received characters may be transmitted, via a communication link 66 , to a central laboratory 58 for checking, decoding, and or general evaluation.
- the pattern of the assaying means 32 , the condition of the adulteration detection means 36 and the quality control indication means 38 , and the identification code may be provided as “machine readable” and may be transmitted in an anonymous and confidential manner to the central laboratory 58 , in accordance with the privacy features of present invention.
- Those skilled in the art will appreciate the available means to embody the test card 22 of FIG. 1A , and further may provide modifications and alterations to the embodiments of the test card reading apparatus 60 of FIGS. 2 and 3 .
- test card reading apparatus 60 is seen in FIG. 3 .
- a scanner 54 a and decoder 54 b configured to read the test card 22 and decode the plurality of patterns contained thereon.
- the patterns may include the assaying means 32 , the identification code 42 , the adulteration detection means 36 , and the quality control indication means 38 .
- a controller module 62 is provided to establish the functional characteristics of the test card reading apparatus 60 .
- the controller module 62 may be embodied as shown by providing a processor 62 a, a memory unit 62 b (providing a suitable application program), and any required interface circuitry 62 c.
- the controller module may be arranged to receive from the decoder information including one or more (decoded) digits or characters.
- the information may then be transmitted by a communication module 63 via the communication link 66 to the central laboratory 58 .
- the information processed and or transmitted to the central laboratory 58 for analysis.
- a user interface module 64 to enable an individual to enter information into the test card reading apparatus 60 and provide information to said individual.
- the user interface may include known items such as a display 64 a, a keyboard 64 b, an audio unit 64 c, and printer 64 d.
- an identification code such as the donor's social security number may be keyed into the keyboard 64 B of the user interface module 64 and transmitted via the communication link 66 to the central laboratory 58 .

The disclosures of the aforementioned applications are, by reference, incorporated herein.
- 1. Field of the Invention
- The invention relates to an assaying system. More particularly, the invention relates to a machine readable assaying system for analyzing a specimen of physiological fluid to detect the presence or absence of particular substances therein. In a preferred embodiment, the machine readable assaying system contemplates the utilization of machine readable bar-code patterns imprinted upon a test card which change form in response to a physical, chemical or biological reaction. The test result which is encoded within the bar-code indicia imprinted upon the test card is read by an appropriate decoding apparatus (i.e. a bar-code reader/scanner), and the decoded results are stored in a memory unit and transmitted, if desired, to a distinct location. A test administrator merely scans the bar-code. Because the bar-code patterns change form in such a subtle yet varied manner, the administrator or another observer of the test card is unable to discern the results. Accordingly, the privacy interests of the donor are preserved, as well as human interpretation errors, transcription and translation errors.
- The increase in drug use over the past several decades has created a sharp need for more effective, expeditious methods of analyzing whether a particular individual is a user of certain illegal substances. Both private industry employers as well as governmental employers often need to determine whether an individual has drug residue present in his or her biological system, and hence determine whether such an individual is a drug user or drug abuser and thus an unqualified employee.
- Typically, the status of an individual as a drug user or abuser is determined by analysis of the individual's physiological fluids, namely urine. A specimen of urine is collected, and a highly sensitive screening test is first performed, usually at a centralized laboratory. If specimen samples screen positive at the central laboratory, then a more sensitive and controlled confirmation analysis must be performed.
- In addition to being an extremely costly process, the above mentioned procedure also involves great time delays to employers desirous of obtaining new qualified employees. Upon collection of the urine sample, the employer must wait to receive test results from the central laboratory before hiring any potential employees. Furthermore, the massive amount of handling and transfer of the sample of urine from the initial collection site to the central laboratory.
- To combat the above mentioned timeliness problem which faces many employers in awaiting results from the central laboratory, various “on-site” or “hand-held” assaying devices have been developed. A major problem inherent in these “on-site” testing devices is that the privacy concerns of the potential employee being tested are not adequately addressed. Since all of the on-site testing devices available heretofore attempt merely to identify drugs present (i.e. simply to indicate which specimens do indeed possess the prohibited substance/drug), the anonymity of a presumptive positive donor is impossible to conceal. Due to such lack of anonymity, many employers (governmental in particular) will not employ such an assaying system as it does not comply with federally mandated regulations regarding privacy and civil liberties during drug-employment testing. A more anonymous, reliable and expeditious assaying system is needed, wherein negative results can be obtained quickly without compromising the privacy concerns of the tested individual. The results are not “human readable” and thus are not subject to interpretation.
- It is an object of the invention to produce an assaying system for analyzing a specimen of body fluid to detect the absence of particular substances therein.
- It is another object of the invention to provide an assaying system which provides more anonymous, reliable and expeditious results than those assaying systems presently found in the art, wherein said results can be obtained quickly without compromising the privacy concerns of the tested donor individual.
- It is a further object of the invention to provide an on-site, portable assaying system which allows the results of said assay to be determined and utilized almost immediately by an employer, without jeopardizing the privacy rights of the individual being tested.
- It is a still further object of the invention to provide an assaying system which allows the results of said assay to be encoded in a machine readable format (such as bar-coding) such that said encoded results are visually undetectable and must be de-coded by appropriate apparatus. Accordingly, the administrator of the assay lacks access to the test results.
- It is yet another object of the invention to provide an assaying system which possesses a memory unit to store resultant decoded assay data, and communication means for transmitting said decoded data to a distinct location (such as a central laboratory/processing office). Upon receiving the assay data, the central laboratory/processing office could then electronically, telephonically or manually (via a delivered hard copy) communicate a responsive “negative test certificate” to the employer for those individuals testing negative (indicating that these individuals are candidates for immediate employment). A sample specimen of physiological fluid from only those individuals who tested positive would then be requested by the central laboratory for standard “confirmation” testing.
- It is yet another object of the invention to provide an assaying system such as that discussed above which possesses means capable of detecting adulteration of the specimen.
- To the accomplishment of the above and related objects the invention may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact, however, that the drawings are illustrative only. Variations are contemplated as being part of the invention, limited only by the scope of the claims.

FIG. 1B illustrates an enlarged portion of the embodiment of the test card ofFIG. 1A . -
FIG. 2 is a high level functional diagram of an embodiment of an assaying system apparatus to read/interpret the test card ofFIG. 1A in accordance with the invention. -
FIG. 3 provides a more detailed block diagram of an embodiment of if the apparatus ofFIG. 2 . -
FIG. 4 provides another embodiment of an apparatus to read/interpret test cards of the present invention. -
FIG. 1 depicts atest card 22 of an on-site machine readable assaying system, having various indicia inscribed thereupon. More specifically, thetest card 22 possesses machine readable assaying means 32 (also to be referred to hereafter as an encoded machine readable data source). The machine readable assaying means 32 preferably comprise in part a plurality of individual analysis strips 34, each consisting of antibodies and/or reagents capable of chemically analyzing a sample volume of urine to detect a positive presence of a particular substance (such as marijuana, opiates, amphetamines, cocaine, PCP, etc.). Traditionally, assaying means in this particular field were configured merely to visually indicate the positive presence of particular substances. If a “positive” indication was given, it was automatically inferred that the donor individual who provided the urine was a drug user/abuser (although secondary testing is always conducted to confirm these results). This system posed great threats to individual privacy and civil liberty concerns, and hence proved unsatisfactory. The employment of the assaying means by the instant invention, however, addresses these deficiencies. - As seen in detail in
FIG. 1B , the plurality of individual analysis strips 34 are illustrated as an essential component of the machine readable assaying means 32 (also referred to as bar code indicia). As mentioned earlier, each of said analysis strips 34 consists of the antibodies and/or reagents which are capable of visually indicating the positive presence of distinct illicit substances. In particular, the machine readable assaying means 32 may be formed, as shown inFIG. 1B , of a pattern of elements including one or morefixed strips 33 a, one or moreblank regions 33 b, and the analysis strips 34, to produce the encoded machine readable data source. In a preferred embodiment, the detection of the presence of a particular substance or drug will result in one or more of the analysis strips 34 changing from a first (light reflective) color to a second darker (light absorbent) color—or visa versa. - As seen in the arrangement depicted in
FIG. 1B , the pattern of analysis strips 34, fixed strips 33A, and blank regions 33B (which may also be termed “bars” and “spaces” by those skilled in the art), when configured to comprise the encoded machine readable data source may be provided to encode one or more characters/digits of information or other data. Accordingly, by the inclusion of the analysis strips 34 along with the plurality of fixedstrips 33 a andblank regions 33 b, the detection of one or more illicit substances may cause the overall pattern of fixed 33A and test 34 strips (bars) and blank regions 33B (spaces) to vary, and hence the encoded information represented thereby to be altered. For example, machine readable assaying means 32 comprising the encoded machine readable data source may be comprised of one or more bar code indicia whose pattern of bars and spaces (and associated coded digits) is altered in accordance to the particular substances detected via the inclusion and appearance of one or more analysis strips 34 within the bar code indicia. Accordingly, the particular pattern of bars and spaces that result from an exposure the physiological fluids of a donor, as provided by the machine readable assaying means 32, is contemplated to produce a distinct machine readable indicia. - It is contemplated in the preferred embodiment that one or more of the individual analysis strips 34 which comprise the bar code indicia of the machine readable assaying means 32 contain reagents or antibodies whose visual appearance is altered in response to physiological fluid, regardless of whether any illicit drugs are present within said fluid. It is further contemplated that these “control” analysis strips 34C be situated such that their detection amongst the pattern of
strips 33A and 34 and blank regions 33B (bars and spaces) comprising the bar code indicia does not vary the character of the information encoded therewithin. For instance, the bar code indicia of the machine readable assaying means 32 would indicate, if decoded by an appropriate device prior to contact with physiological fluid, a negative presence of illicit drugs. Upon contact with a volume of physiological fluid which lacks the presence of illicit drugs, the “control” analysis strips 34C will appear. However, their placement amongst the standard test strips 34, fixed test strips 33A and blank regions 33B will not effect the initial encoded character of the bar code indicia. Accordingly, a negative assay will be determined. - The function of the “control” analysis strips 34 is to prevent an administrator of the test from learning the outcome of the assay. If, subsequent to the administration of each assay, some type of change occurs to the visual appearance of the machine readable assaying means 32, then the test administrator will be unable to discern positive test results from negative results. Only the device used to decode the encoded bar code indicia will be able to determine whether the donor's specimen of physiological fluid tests positive for illicit drugs, and if so, which particular substances were present.
- The
test card 22 ofFIG. 1A also possesses adulteration detection means 36. Said adulteration detection means 36 are capable of determining whether a particular specimen of urine or other physiological fluid has been tampered with by administering either chemical analysis (to ensure that the chemical composition of said specimen is consistent with that of standard, non-adulterated human urine) and/or temperature analysis (to ensure that the specimen has been recently excreted from the donor and has not been brought to the test site by the donor from an earlier excretion). Furthermore, quality control indication means 38 are also present upon saidtest cards 22 to ensure that the reagents of the analysis strips 34 are functioning properly. Said quality control indication means 38 are configured to generate a signal upon contact with urine or other physiological fluids, regardless of the presence of illicit substances, to indicate that the analysis strips 34 have not been degraded due to improper storage, etc. If the quality control indication means 38 fail to generate a signal upon contact with the urine, thetest card 22 should be discarded. - Further included upon the
test card 22 ofFIG. 1A is anidentification code 42, which may be provided as a pattern encoding items such as production batch numbers of the test card, a date of manufacture, etc. It is important to note that theidentification code 42 pattern represents a machine readable (and decodeable) pattern, and as such may easily be “read” by a suitable device and received by a computer or controller means for processing, dissemination, or other appropriated actions. - Also seen in
FIG. 1A are alignment aids 46 that may be provided to aid in the alignment of thetest card 22 for reading or scanning by a properly arranged device. It is important to note that other arrangements of theidentification code 42, the quality control indication means 38, the adulteration means 36, and the assaying means 32 are possible and contemplated. For example, skilled persons will appreciate modifications such as including the quality control indication means 38 and the adulteration means 36 within the elements composing the assaying means 32, as seen inFIG. 1B . Accordingly, quality control indication means 38 and the adulteration means 36 may determine the overall “coding” provided by said assaying means 32. In one embodiment of the instant invention, it is contemplated that the quality control indication means 38 be incorporated with the “control”test strips 34 and situated such that their detection amongst the pattern ofstrips 33A and 34 and blanks 33B (bars and spaces) comprising the bar code indicia does not vary the character of the information encoded therewithin. Still other modifications are possible and contemplated. - Turning now to
FIG. 2 , there is provided a high level functional diagram of a testcard reading apparatus 60. As shown, a testcard reading unit 54 is included, which is operatively coupled to a control and communication means 56. The test card reading means 54 is provided to “read” and determine the particular patterns present on thetest card 22. As such, the reading of the patterns of thetest card 22 may result in a plurality of digits or characters being determined (or generated) by the testcard reading units 54, which may be communicated to a control and communication means 56. Subsequently, the received characters may be transmitted, via acommunication link 66, to acentral laboratory 58 for checking, decoding, and or general evaluation. Therefore, the pattern of the assaying means 32, the condition of the adulteration detection means 36 and the quality control indication means 38, and the identification code may be provided as “machine readable” and may be transmitted in an anonymous and confidential manner to thecentral laboratory 58, in accordance with the privacy features of present invention. Those skilled in the art will appreciate the available means to embody thetest card 22 ofFIG. 1A , and further may provide modifications and alterations to the embodiments of the testcard reading apparatus 60 ofFIGS. 2 and 3 . - One possible embodiment of the test
card reading apparatus 60 is seen inFIG. 3 . Included is ascanner 54 a anddecoder 54 b configured to read thetest card 22 and decode the plurality of patterns contained thereon. The patterns may include the assaying means 32, theidentification code 42, the adulteration detection means 36, and the quality control indication means 38. A controller module 62 is provided to establish the functional characteristics of the testcard reading apparatus 60. The controller module 62 may be embodied as shown by providing aprocessor 62 a, amemory unit 62 b (providing a suitable application program), and any requiredinterface circuitry 62 c. The controller module may be arranged to receive from the decoder information including one or more (decoded) digits or characters. The information may then be transmitted by a communication module 63 via thecommunication link 66 to thecentral laboratory 58. The information processed and or transmitted to thecentral laboratory 58 for analysis. Also shown is auser interface module 64 to enable an individual to enter information into the testcard reading apparatus 60 and provide information to said individual. The user interface may include known items such as adisplay 64 a, akeyboard 64 b, anaudio unit 64 c, andprinter 64 d. For example, an identification code such as the donor's social security number may be keyed into the keyboard 64B of theuser interface module 64 and transmitted via thecommunication link 66 to thecentral laboratory 58. Other user interface items may also be provided (which are not shown inFIG. 3 ) including pointing devices, a fax transmission module, touch screen displays, etc. - It should be noted that the controller module 62 may be provided by known programmable single chip microcomputers and any additional analog/digital circuitry required. Further, it is contemplated that the controller module 62 may be provided (in an alternate embodiment to that shown in
FIG. 3 ) by one or more programmable logic devices (PLDs), or by discrete components including digital MSI and LSI logic functions. Those skilled in the art will appreciate the plethora of commercially available (off-the-shelf) devices and components that may be utilized to embody the controller module 62 and the communication module 63. Also, although thescanner 54 b may in a preferred embodiment be realized by a laser scanning device, other suitable devices, such as a CCD imaging device may be employed. It is also contemplated that the testcard reading apparatus 60 may be realized by a properly configured personal or workstation computer. For example, an IBM.®. compatible personal computer (PC) may be arranged with ascanner 54 a, a fax modem or networking card, etc. In such an embodiment, the functionality of the testcard reading apparatus 60 may be provided by the execution of an (custom) application program. Therefore, it should be understood that the embodiments of theFIGS. 3 and 4 are illustrative of a number of possible embodiments, which may be provided by skilled persons. - Another embodiment of the test
card reading unit 54 ofFIG. 2 is provided inFIG. 4 . An important feature of this invention is the use of an “interpretation means”, such asinterpreter 72, which will “read” thetest card 22, along with anencoder 76 that may be employed to generate (e.g. print) aresult summary 82. Theresult summary 82 is contemplated to include one or more printed bar code indicia. In a preferred embodiment of the present invention, theresult summary 82 may be provided (printed) using standard bar code symbologies (such as Code 39, Interleaved 2 of 5, PDF417, etc.), and accordingly could be read using “off-the-shelf” scanning devices and decoders to providescanner 54 a anddecoder 54 b ofFIG. 3 . An advantage of the arrangement ofFIG. 4 , is that the assaying means 32 need not be configured initially in a “standard” bar code indicia. For instance, rather than configuring the machine readable assaying means 32 in standard bar code language format, a customized configuration can be employed (by using, for instance, optical scan sheets). It is the function of theinterpreter 72 and theencoder 76 to then decipher this customized configuration and provide a standard bar code indicia (that is scannable by low cost and known devices and apparatus). - The aforementioned configuration of the machine readable assaying system of the instant invention render said system capable of being employed on-site at an employer's individual location. A donor individual is given a collection container and provided a private environment where said donor individual is to excrete a specimen volume of urine into the collection container for analysis. A volume of urine is then brought into contact with the test card 22 (by bathing the
test card 22 with a small amount of urine, inserting thetest card 22 into the urine, etc.) The quality control indication means 38 and/or thecontrol test strips 34 are then checked to assure the integrity of the assaying means 32. Assuming that the assay is functioning properly, the adulteration detection means 36 are then checked to determined whether the donor individual tampered with the specimen. If the adulteration detection means 36 indicate that the specimen is unadulterated, then the machine readable assaying means 32 are then read by the test card reading unit 54 (such as thescanner 54 a anddecoder 54 b). The results of the assay are then stored in the memory unit 62B of the controller module 62 for transmission to a desired location such as thecentralized laboratory 58. - Upon the
central laboratory 58 receiving the assay data, the names or identification codes of those donor individuals who provided negative results may be immediately communicated to prospective employers, so that those particular donors may be offered employment. All positive assay urine specimens will be requested from the test site by thecentral laboratory 58 for further confirmation analysis. Accordingly, the employer is immediately provided with a number of qualified potential employees to choose from, and the privacy concerns of the donor individual are safeguarded.
