Assay test strips and reading same
First Claim
1. An assay test strip, comprising:
- a flow path for a fluid sample;
a sample receiving zone coupled 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 that comprises an immobilized test reagent and a control region that comprises an immobilized control reagent,wherein the test reagent and control reagent are immobilized in discrete code areas forming a bar code pattern that encodes information.

Abstract
An assay test strip includes a flow path, a sample receiving zone, a label, a detection zone that includes a region of interest, and at least one position marker. The at least one position marker is aligned with respect to the region of interest such that location of the at least one position marker indicates a position of the region of interest. A diagnostic test system includes a reader that obtains light intensity measurement from exposed regions of the test strip, and a data analyzer that performs 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.
