Hepatitis B is a viral infection that affects the liver. It is caused by the hepatitis B virus (HBV), which is primarily transmitted through direct contact with infected bodily fluids. While some individuals with hepatitis B experience a short illness lasting only a few weeks, others develop a serious, lifelong illness known as chronic hepatitis B.

The hepatitis B vaccine, commonly administered during childhood, is very effective at preventing infection. For those unsure about their vaccine status, immunity to the hepatitis B virus can be assessed with eNational’s blood test.

Who should take this test?

This test is used to assess immunity to the hepatitis B virus, either from a previous infection or vaccination. It is appropriate for anyone concerned about their susceptibility to hepatitis B. It is especially useful for those working in healthcare and laboratory settings who may be at increased risk of exposure.

What is included in this test?

This blood test screens for:

• HBsAg antibodies

This quantitative test measures the concentration of antibodies against the hepatitis B surface antigen (HBsAg) in the bloodstream. It provides a numerical value indicating the strength of the immune response to hepatitis B.

How will taking this test benefit me?

Hepatitis B can cause serious, lifelong illness. Confirming your immunity can provide peace of mind, especially for those at increased risk of exposure.

Most people who receive the full hepatitis B vaccine series develop long-lasting immunity. However, some individuals may experience a decline in antibody levels over time. A booster vaccine may be recommended if antibody levels are insufficient.
