Patent attributes
In accordance with certain disclosed embodiments of the present invention, there is provided an assay test device for determining whether a fluid under test contains a certain substance, wherein the device includes a test strip disposed at least partially within a housing for receiving the fluid under test. A sensor mounted on the housing detects the certain substance in the fluid under test received on the test strip to generate an electrical signal indicative of the amount of the substance detected. A processor responds to the signal for determining whether or not the fluid under test contains a predetermined quantity of the certain substance to generate an electrical signal. A display mounted on the housing responds to the output signal to indicate the presence or absence of a predetermined quantity of the certain substance contained within the fluid under test.
