Details of Hepatitis B Surface Antigen (Hbsag) - Spot / Rapid Test
What is Hepatitis B Surface Antigen (Hbsag) - Spot / Rapid Test?
Hepatitis B Surface Antigen (HBsAg), also known as Australia antigen is present on the surface of the Hepatitis B virus (HBV). This test detects the presence of Hepatitis B Surface Antigen (HBsAg) in the blood.
  • To detect Hepatitis B virus infection in patients having symptoms suggestive of Hepatitis
  • To screen for Hepatitis B infection following accidental exposure to HBV e.g. in healthcare workers. Repeat testing is recommended after 6 weeks post-exposure
  • To screen for Hepatitis B infection in individuals who are at risk of acquiring infection like IV drug users, sex workers, hemodialysis patients, prisoners, etc.
  • To screen for Hepatitis B infection during pregnancy to prevent transmission of infection from mother to child
Hepatitis B is an infection of the liver caused by the Hepatitis B virus (HBV). HBV is one of the major causes of acute and chronic hepatitis, cirrhosis, and hepatocellular carcinoma, and it is a serious global public health problem. It is estimated that 350 million individuals worldwide are infected with the virus, which causes 620,000 deaths each year. People most at risk include antibody who has unprotected sexual intercourse, drug users who share needles and syringes, health care workers in contact with potentially contaminated blood or body fluids, anyone in intimate contact with the infected person. Therefore, the development of economic and accurate detection systems and potential alternative antiviral approaches for HBV detection could be important for fighting viral hepatitis. Hepatitis B diagnosis has been based on the detection of serologic markers.

Testing for these markers helps to determine the presence of past or ongoing HBV infection, the acute, chronic, or subclinical carrier state of the disease, response to therapy, and/or the immune status of the patient. Hepatitis B virus surface antigen (HBsAg) is the first serological marker to appear in the circulation, well before clinical symptoms, and is the viral component usually found in the highest concentration in the serum of HBV-infected patients. The presence of anti-HBs in serum indicates previous exposure to HBV and long-lasting acquired immunity. Low serum titers of anti-HBs, however, can signal a lack of immunity to future HBV infection. In this study, diagnostic systems based on the use of a monoclonal antibody (MAb) and polyclonal antibodies (PAb) were developed and conjugated enzyme and biotin for early and sensitive diagnosis of Hepatitis B which is still one of the important infectious diseases in Turkey. Sandwich ELISA kit systems were generated by using both 2G3 MAb (as capturing agent) and 2G3-HRP or 2G3-biotin conjugates (as detecting agents).

Homemade sandwich ELISA tests were compared with the other conventional sandwich ELISA tests by using hepatitis B positive and negative infection serum. They were shown that our system gave reliable results. When the homemade HBsAg ELISA system was compared with the other commercial kit by using 280 patients’ sera, it was shown that our system corresponded with the results of negative and positive samples at a ratio of 96 %. When the homemade anti- HBsAg ELISA system was compared with the commercial kit by using 173 patients’ sera, it was shown that our system corresponded with the results of negative and positive samples at a ratio of 91 %. In subsequent studies by the final tests of homemade ELISA kit, it was observed that Biotin-labeled kits responded very close results with the 97% conformity level when compared with commercial kits.
