Immunochromatographic assay

The HBsAb Hepatitis B Surface Antibody Test Whole Blood (Strip) is a rapid, immuno-chromatographic assay for the detection of antibodies to Hepatitis B surface antigen (HBsAb)in whole blood, human serum, or plasma. The test provides a visual, qualitative result and is intended for professional use.

Test Procedure:

1. Bring the pouched test strip to room temperature(15-30℃) prior to testing. Do not open the 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. Use the pipette to slowly draw and add 2 drops of whole blood to the sample pad, then hold the buffer bottle vertically and add 1 drop of the buffer.
4. Wait for colored lines to appear. Interpret test results between 15-20 minutes. Do not read results after 20 minutes.

• 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 the problem persists, contact your local distributor.)
