The lateral flow assay represents an improvement in the ability to accurately and with high fidelity to detect the presence or absence of a target analyte in a liquid sample, in part, by encompassing a reference region of {HEAD ~ immobilized, non diffusible analyte} that allows for {TAIL ~ detection} of any factors that interfere with the interaction and binding of the analyte to the labeled capture reagent
