2. 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 Cvirus. The complex antigen found on the surface of HBV is called HBsAg. The presence of HBsAg in whole blood, serum or plasma is an indication of an active Hepatitis B infection, either acute orchronic. The antibody to HBsAg, HBsAb may not become detectable for 3-6 months after acute infection. It is as the marker of immunity to HBV. As a result, vaccination against HBV was introduced to control the morbidity and mortality associated with the virus. As part of the World Health Organization (W.H.O) program for the control of Hepatitis B, many people especially new born infants, receive vaccination.

3. Principle

The HBsAb Antibody Test (whole blood/Serum/Plasma) is a lateral flow chromatographic immunoassay based on the principle of the double antigen-sandwich technique. The membrane is pre-coated with an HBsAg antigen on the test line region of the test. During testing, The specimen (whole blood, serum or plasma)  reacts with the particle coated with HBsAg antigen. The mixture migrates upward on the membrane chromatographically by capillary action to react with HBsAg antigen on the membrane and generate a colored line. 

The presence of this colored line in the test region indicates a positive result, while its absence indicates a negative result.

5. Quality Control

A procedural control is included in the test. A red line appearing in the control region (C) is the intermal procedural control. It confirms sufficient specimen volume and correct procedural technique
