INTENDED USE: Hepatitis B Surface Antibody Test is a rapid, immunochromatographic assay for the detection of antibodies to Hepatitis B surface antigen (HBsAb)in human serum or plasma. The test provides a visual,qualitative result and is intended for professional use.
1. Bring the pouched test strip to room temperature(15-30℃) prior to testing. Do not open pouch until ready to perform the assay.
2. Remove the test strip from the sealed pouch. Lay it on a flat, clean and dry surface.
3. Immerse the test strip in the specimen with the arrow end pointing toward the specimen solution. Do not immerse the strip above the printed MAX line. After a minimum of 15 seconds, remove the test strip from the specimen solution and lay flat on a non-absorptive clean surface. Alternatively, the test strip may be left in the
test specimen as long as the strip is not immersed above the MAX line. A separate test strip must be for each specimen or control.
4. Wait for colored lines to appear. Interpret test results between 15-20 minutes. Do not read results after 20 minutes.
INTERPRETATION OF RESULTS
Positive Negative Invalid
Positive:Two colored lines should be observed in the result area, one in the test region and another one in the control region. The color intensity of the test line may be weaker or stronger than that of the control line.
Negative:Only the control line appears in the result area.
Invalid: No line appears in the control region regardless of the presence or absence of the test line.
NOTE: Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for the control line failure. Review the procedure and repeat the test with a new test strip. If problem persists, please contact your local distributor.
