Principle : The fast detector one step pregnancy test is a rapid , one – step lateral flow immunoassay in device format for the qualitative detection of human chorionic gonadotropin (HCG) in urine to aid in the detection of pregnancy . the test utilizes a combination of antibodies including a monoclonal HCG antibody to selectively detect elevated levels of HCG . The assay is conducted by adding urine to the specimen well , and obtaining the result from the colored lines. Specifications: -Easy to use -Sensitivity: 25mIU/ml -Reaction Time: 3-5 minutes The procedure: 1.Collect the urine . Remove the test cassette from the sealed pouch. 2.Hold the dropper vertically and transfer 2-3 full drops of urine (approx.80-100ul) to the sample well of the test cassette. 3.Observe the test result immediately within 5 minutes . the result is invalid over 10 minutes . Result judgment : Positive : two distinct red lines appear . one line should be in the control region(C) and another line should be in the test region (T). Negative : one line appears in the control region(C). No apparent red or pink line appears in the test region(T). Invalid : no red bands appear or control line fails to appear , indicating operator error or reagent failure .
