HBsAg / HBsAb Tests

HBV ( Hepatitis B Virus ) , that cause of chronic hepatitis is classified as a hepadnavirus. It is a major factor in the eventual development of liver disease and hepato cellular carcinoma in the individuals. HBV has three major antigens consists of HBsAg , HBcAg , and HBeAg.
HBsAg is firstly appear when patient is infected by hepatitis B virus and usually detectable 2 - 6 weeks in advance of clinical and biochemical evidence of hepatitis and persist throughtout the clinical course of the disease but typically disappears by the sixth month after exposure. Antibody to HBsAg is first detected at a variable period after the disappearance of HBsAg. This rapid diagnostic of HBV infection is essential to patient management and disease control.
The development of rapid immuno-chromatographic assay of HBsAg is an initial screening test for the detection of HBV infection from patient's serum / plasma specimens.
The development of a rapid immuno-chromatographic assay of HBs Antibody is an initial screening test for the detection of abtibody to HBs as low as 10 mIU / ml from patient's serum / plasma.
