Abstract
In one aspect, an assay test strip includes a test label that specifically binds a target analyte and a control label that is free of any specific binding affinity for the target analyte and has a different optical characteristic than the test label. In another aspect, an assay test strip includes a test label that specifically binds a target analyte and at least one non-specific-binding label that is free of any specific binding affinity for the target analyte. Systems and methods of reading assay test strips also are described.

29. A diagnostic test system, comprising:
-
a reader operable to obtain light intensity measurements from exposed regions of an assay test strip comprising a detection zone; and a data analyzer operable to perform operations comprising determining a test measurement value from light intensity measurements obtained from a test label bound to a region in the detection zone containing a first immobilized reagent, determining a compensation measurement value from light intensity measurements obtained from a compensation label different from the test label in one or more regions of the detection zone free of immobilized reagents that specifically bind the compensation label, and determining a parameter value from the test measurement value and the compensation measurement value. - View Dependent Claims (30, 31, 32, 34, 35)
