Method of detecting an analyte for lateral flow immunoassay tests

摘要

A visual perception of a colored site in an immunoassay device comprising a strip for enabling capillary migration of a fluid sample therealong, a labeled reagent disposed on the strip and formulated for suspension in the sample migrating therepast and a captive reagent immobilized on the strip in a path of sample migration and formulated to bind to is enhanced by changing a color of the strip to the color which is complimentary to the colored site.
