Hepatitis B Surface Antibody
Hepatitis B is an infectious disease affecting the liver, caused by the hepatitis B virus (HBV). The infection is often asymptomatic, but once established, it can progress to chronic scarring of the liver (fibrosis and cirrhosis). In some cases, those with cirrhosis will go on to develop liver failure or other complications of cirrhosis, including liver cancer. The hepatitis B virus (HBV) is spread by blood-to-blood contact. Fasting is not required for this test. Take all medications as prescribed.
