The Cardiac Troponin I Rapid Test Cassette (Whole Blood/Serum/Plasma) is a qualitative, membrane based immunoassay for the detection of cardiac Troponin l(cTnl) in whole blood, serum or plasma. In this test procedure, capture reagent is immobilized in the test line region of the test. After specimen is added to the specimen area of the cassette, it reacts with anti-cTnl antibody coated colloid gold particles in the test. This mixture migrates chromato graphically along the length of the test and interacts with the immobilized capture reagent. The test format can detect cardiac Troponin l(cTnl) in specimens. If the specimen contains cardiac Troponin l(cTnl), a colored line will appear in the test line region, indicating a positive result. If the specimen does not contain cardiac Troponin (cTnl), a colored line will not appear in this region, indicating 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.
