One Step CEA in whole blood Rapid Screen Test is a lateral flow, immunochromatographic screening test. Purified antibodies of carcino-embryonic antigen(CEA) are precoated onto membrane as a capture reagent on the test band region.If CEA is present in the sample in concentration above the labeled anti-human IgG-dye complex will be formed. This complex is then captured by CEA immobilized in the Test Zone of the membrane, producing a visible pink-rose color band on the membrane. The color intensity will depend on the concentration of the CEA present in the sample. This one step test is very sensitive and only takes about 15 minutes. Test results are read visually without any instrument.
For whole blood, collect blood into a container with anticoagulant. If the specimen cannot be tested on the day of collection, store the whole blood specimen in a refrigerator. Bring the specimens to room temperature before testing.
