Hepatitis B is a viral infection that affects the liver and can cause both acute and chronic disease. The infection is transmitted through contact with infected blood or body fluids, including through sexual contact, sharing needles, or from mother to child during childbirth. Many people with hepatitis B do not experience symptoms initially, which is why laboratory testing plays a crucial role in diagnosis and monitoring of the infection.

Several laboratory tests are available to detect and monitor hepatitis B infection. The hepatitis B surface antigen test, known as HBsAg, is the primary screening test used to determine if someone has an active infection. If this test is positive, it indicates the presence of the virus in the bloodstream. Additional tests include hepatitis B surface antibody, which shows immunity either from vaccination or recovery from past infection, and hepatitis B core antibody tests that help distinguish between acute and chronic infections or past exposure to the virus.

For people diagnosed with hepatitis B, regular monitoring through blood tests is essential to assess liver function and determine the stage of disease. Liver function tests measure enzymes and proteins in the blood that indicate how well the liver is working. The viral load test, which measures the amount of hepatitis B DNA in the blood, helps doctors evaluate disease activity and determine if antiviral treatment is needed. Additionally, tests for alpha-fetoprotein may be recommended as this marker can be elevated in people with chronic hepatitis B who develop liver complications.

Understanding hepatitis B test results requires interpretation by healthcare providers who can explain what the various markers mean for an individual's health status. Testing is recommended for people at higher risk, including those born in areas where hepatitis B is common, people with HIV infection, healthcare workers, and anyone who may have been exposed to the virus. Early detection through laboratory testing allows for appropriate medical management and helps prevent transmission to others.
