HBcAb Rapid Test Strip
FOR THE QUALITATIVE ASSESSMENT OF HBcAb IN HUMAN SERUM, PLASMA OR WHOLE BLOOD
The One Step HBcAb Test is a rapid chromatographic immunoassay for the qualitative detection of Hepatitis B virus core antibody (HBcAb/anti-HBc) in Whole Blood /Serum / Plasma.
The One Step HBcAb Test is a competitive immunoassay. Colloidal gold conjugated anti-HBcAg antibody complexes are dry-immobilized in the test device. When the specimen is added, it migrates with the gold conjugate complexes by capillary diffusion through the strip. If present, HBcAb will compete with gold conjugate complexes for the limited amount HBcAg immobilized in the Test Zone (T). It will prevent the gold conjugate complexes from reacting with HBcAg and no red line appears in the Test Zone (T). If there is no HBcAb in the specimens, gold conjugate complexes will react with HBcAg and a visible red line appears. To serve as a procedural control, a red line will always appears in the Control Zone (C) which indicates the validity of the test.

Specimen Collection and Preparation
1.The One Step HBcAb Test can be performed used on Whole Blood /Serum / Plasma.
2.To collect whole blood, serum or plasma specimens following regular clinical laboratory procedures.
3.Separate serum or plasma from blood as soon as possible to avoid hemolysis. Use only clear non-hemolyzed specimens.
4.Testing should be performed immediately after specimen collection. Do not leave the specimens at room temperature for prolonged periods. Serum and plasma specimens may be stored at 2-8℃ for up to 3 days. For long term storage, specimens should be kept below -20℃. Whole blood should be stored at 2-8℃ if the test is to be run within 2 days of collection. Do not freeze whole blood specimens.
5.Bring specimens to room temperature prior to testing. Frozen specimens must be completely thawed and mixed well prior to testing. Specimens should not be frozen and thawed repeatedly.
Allow the test, specimen and/or controls to reach room temperature 15-30℃ (59-86℉) prior to testing.
1.Bring the pouch to room temperature before opening it. Remove the test device from the sealed pouch and use it as soon as possible.
2.Place the test device on a clean and level surface.
3.For serum or plasma specimen: Hold the dropper vertically and transfer 3 drops of serum or plasma (approximately 100μl) to the specimen pad of the test device, then start the timer. See illustration below.
4.For Whole blood specimen:Hold the dropper vertically and transfer 1 drop of specimen (100μl) to the specimen pad of the test device, then add 2 drops of buffer (approximately 70μl) and start the timer. See illustration below.
5.Wait for the colored line(s) to appear. Read results at 15 minutes. Do not interpret the result after 20 minutes.
Applying sufficient amount of specimen is essential for a valid test result. If migration (the wetting of membrane) is not observed in the test window after one minute, add one more drop of specimen to the specimen well.
Interpretation of Results
Positive: One colored line appears in the control region(C).No apparent colored line appear in the test line region.
Negative: Two lines appear. One line should always appear in the control line region(C), and another one apparent colored line should appear in the test line region.
Invalid: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test device. If the problem persists, discontinue using the test kit immediately and contact your local distributor.
