Hepatitis B Screening


Hepatitis B Screening

Hepatitis B is a viral infection that affects the liver and can lead to both acute and chronic diseases. Chronic Hepatitis B infection can cause serious liver problems, including cirrhosis and liver cancer. Screening for Hepatitis B involves blood tests to detect the presence of the virus and assess its activity. Here are the common tests used for Hepatitis B screening:

Hepatitis B Surface Antigen (HBsAg) Test:

This blood test is the primary screening tool for Hepatitis B. It detects the presence of the HBsAg protein on the surface of the virus. A positive result indicates current infection.

Hepatitis B Surface Antibody (anti-HBs) Test:

This test measures antibodies against the Hepatitis B surface antigen. A positive result indicates immunity, either from a past infection or vaccination.

Sample Requirement

Blood Sample Type:

Venous Blood: A venous blood sample is most commonly used for Hepatitis B Screening. It is drawn from a vein, usually in the arm, using a needle and a collection tube.
