ABSTRACT:
In accordance with certain disclosed embodiments of the present invention, there is provided a method of analyzing assay test results for determining whether a fluid under test contains a certain substance. The disclosed method 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 disclosed method further includes responding to the signal, and determining whether or not the fluid under test contains a predetermined quantity of the certain substance to generate an electric output signal. The method disclosed also includes responding to the 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 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. The stored information is compared with stored threshold electric signals to determine whether or not the fluid under test contains a predetermined quantity of the certain substance.
