The Purpose of a Hepatitis B Surface Antibody Quantitative Test

Hepatitis B is a version of viral hepatitis. This type of liver disease is contagious if you come into contact with bodily fluids from someone with hepatitis B. People are at higher risk if they engage in unsafe sex, share drug needles, or work in healthcare settings, among other situations. Hepatitis B can be mild, resolving after a brief period of time. However, in some cases the virus lingers, and this chronic form of the disease can increase the odds of liver disease or cancer. (One good way of preventing hepatitis B? Getting the vaccine that prevents the disease.).

What Does the Hepatitis B Surface Antibody Quantitative Test Measure?

The hepatitis B surf ab quant test measures the level of antibodies your immune system produces to fight the hepatitis B virus.

Who Should Take a Hepatitis B Surf AB Quant Test?
