Abstract

A strip and apparatus are provided for determining the presence of an analyte in a liquid by inserting the strip into the passageway of the apparatus. Means are provided for rapidly affirming that the strip has been fully inserted right side up with respect to the apparatus.
Specifically, the strip has been provided, at the insertion end of the strip, with apparatus detectable means for cooperating with detection means at the corresponding end of the strip passageway of the apparatus. The apparatus can then be programmed to determine whether or not the insertion end of the strip has reached this point in the passageway.
Additionally, the extreme portion of the strip at the insertion end is provided with an asymmetrical shape for cooperating with a mating configuration in the strip passageway when the strip is inserted right side up.
