HBs Ag rapid test
HBsAg Test Cassette (Serum/Plasma) 30test/kit
HBs Ag rapid test is a immuno-chromatographic (or lateral flow) test for the qualitative detection of Hepatitis B surface Antigen in human serum, plasma or whole blood. It can be used for prenatal or transfusional screening, and during acute infection or chronic carriage of the hepatitis B virus. Early detection of infection is essential for rapid initiation of adequate treatment.
- High performance
- User-friendly and convenient
- First results within 15 minutes
The hepatitis B surface antigen (”HBsAg”) is most frequently used to screen for the presence of this infection. It is the first detectable viral antigen to appear during infection. However, early in an infection, this antigen may not be present and it may be undetectable later in the infection as it is being cleared by the host. The infectious virion contains an inner “core particle” enclosing viral genome. The icosahedral core particle is made of 180 or 240 copies of core protein, alternatively known as hepatitis B core antigen, or ”HBcAg”. During this ‘window’ in which the host remains infected but is successfully clearing the virus, IgM antibodies to the hepatitis B core antigen (”anti-HBc IgM”) may be the only serological evidence of disease.
