{TAIL ~ 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 immobilized, non diffusible analyte that allows for detection of any factors that interfere with the interaction and {HEAD ~ binding} of the analyte to the labeled capture reagent
