TheCEA Rapid Test Device (Whole Blood/Serum/Plasma) is a rapid visual immunoassay for the qualitative presumptive detection of human carcinoembryonic antigen (CEA) 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 CEA Rapid Test Device
TheCEA Rapid Test Device (Whole Blood/Serum/Plasma) detects human carcinoembryonic antigen (CEA) through visual interpretation of color development on the internal strip. CEA antibodies are immobilized on the test region of the membrane. During testing, the specimen reacts with CEA antibodies conjugated to colored particles and precoated onto the sample pad of the test.The mixture then migrates through the membrane by capillary action, and interacts with reagents on the membrane.If there are sufficient CEA antigens in the specimen,a colored band will 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 control region serves as a procedural control, indicatingthat the proper volume of specimen has been added and membrane wicking has occurred.
