【INTENDED USE】 The Amyloid β Protein (Aβ) Rapid Test Cassette is a rapid chromatographic immunoassay for the qualitative detection of Amyloid β Protein in urine for early warning of the risk of dementia as an in vitro screening aid. The test can be used to assess brain health and help doctors determine whether further testing is necessary. 【PRINCIPLE】 The Amyloid β Protein (Aβ) Rapid Test Cassette (Urine) is a qualitative membrane-based immunoassay for the detection of Aβ in urine. It consists of sample pad, conjugate pad, membrane and absorbent pad laid in sequence on apolyvinyl chloride support plate. In this test procedure, capture reagent is immobilized in the test line region of the test. During testing, the urine specimen is dropped into the specimen well, it reacts with monoclonal antibodies recognizing amyloid-ß coated colloid gold particles in the conjugate pad and the mixture migrates upward on the membrane chromatographically by capillary action to react with amyloid-ß binding polymers/antibodies pre-located on the membrane and generate a colored line. The presence of this colored line in the test line region indicates a positive result, while its absence indicates a negative result. To serve as a procedural control, a colored line will always appear in the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.
