HBsAg Rapid Test Cassette

【SUMMARY】
Viral hepatitis is a systemic disease primarily involving the liver. Most cases of acute viral hepatitis are caused by Hepatitis A virus, Hepatitis B virus (HBV) or Hepatitis C virus. The complex antigen found on the surface of HBV is called HBsAg. Previous designations included the Australia or Au antigen. 1 The presence of HBsAg in serum or plasma is an indication of an active Hepatitis B infection, either acute or chronic. In a typical Hepatitis B infection, HBsAg will be detected 2 to 4 weeks before the ALT level becomes abnormal and 3 to 5 weeks before symptoms or jaundice develop. HBsAg has four principal subtypes: adw, ayw, adr and ayr. Because of antigenic heterogeneity of the determinant, there are 10 major serotypes of Hepatitis B virus.

The HBsAg Rapid Test Cassette is a rapid test to qualitatively detect the presence of HBsAg in serum or plasma specimen. The test utilizes a combination of monoclonal and polyclonal antibodies to selectively detect elevated levels of HBsAg in serum or plasma.

【DIRECTIONS FOR USE】
Allow test cassette, serum or plasma specimen, and/or controls to equilibrate to room temperature (15-30 ℃) prior to testing.
1. Remove the test cassette from the sealed foil pouch and use it as soon as possible. Best results will be obtained if the assay is performed immediately after opening the foil pouch.
2. For Serum or Plasma specimen:
Hold the dropper vertically and transfer 3 drops of serum or plasma (approximately 120 μl) to the specimen well of test device and start the timer. See illustration below.
3. Wait for the colored line is appeared. The result should be read at 15~30 minutes. Do not interpret the result after 30 minutes.
