TheAFP Rapid Test Device (Whole Blood/Serum/Plasma) is a rapid visual immunoassay for the qualitative presumptive detection of alpha fetal-protein (AFP) in human whole blood, serum, or plasma specimens.This kit is intended for use as an aid in the diagnosis of various cancers.
Principle of AFP Rapid Test Device
TheAFP Rapid Test Device (Whole Blood/Serum/Plasma) detects alpha fetal-protein (AFP) through visual interpretation of color development on theinternal strip. AFP antibodiesare immobilized on the testregion of the membrane. During testing, the specimen reacts with AFP antibodies conjugated to colored particles and precoated onto the sample pad of the test. The mixture then migrates through the membraneby capillary action, and interacts with reagents on the membrane. Ifthere aresufficientAFP antigensin the specimen, a colored bandwill form at the test region of the membrane. The presence of this colored band indicates a positive result, while its absence indicates a negative result. The appearance of a colored band at the controlregion serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking has occurred.
