Abstract

There is disclosed a method and apparatus for analyzing assay test results for determining whether a fluid under test contains a certain substance. The disclosed method and apparatus includes detecting the certain substance in the fluid under test received on a test strip, and generating an electrical signal indicative of the amount of the substance detected. The method and apparatus disclosed also includes responding to an output signal to indicate the presence or absence of a predetermined quantity of the certain substance contained within the fluid under test. The disclosed method and apparatus includes delaying in the detecting until after a predetermined time delay interval, and storing the detected information at the completion of the time delay interval.
