Abstract
A diagnostic test system includes a housing, a reader, and a data analyzer. The housing includes a port constructed and arranged to receive a test strip that includes a flow path for a fluid sample, a sample receiving zone couple to the flow path, a label that specifically binds a target analyte, a detection zone coupled to the flow path and comprising a test region exposed for optical inspection and having an immobilized test reagent that specifically binds the target analyte, and at least one reference feature. The reader is operable to obtain light intensity measurements from exposed regions of the test strip when the test strip is loaded in the port. The data analyzer is operable to perform operations including at least one of (a) identifying ones of the light intensity measurements obtained from the test region based on at least one measurement obtained from the at least one reference feature, and (b) generating a control signal modifying at least one operational parameter of the reader based on at least one measurement obtained from the at least one reference feature.
