Hepatitis B Surface antigen Blood Tests

The Hepatitis B Surface Antigen test is a blood test that checks for a specific protein on the surface of the Hepatitis B virus. This test is used to determine if a person has been infected with the Hepatitis B virus or if they are a carrier of the virus.

Hepatitis B is a viral infection that affects the liver and can cause serious health problems. It is spread through contact with infected blood or body fluids, such as during unprotected sex, sharing needles, or from an infected mother to her baby during childbirth.

By detecting the presence of the Hepatitis B Surface Antigen in the blood, this test can help diagnose an active infection or determine if someone is a carrier of the virus. A carrier is someone who has the virus in their blood but does not show any symptoms.

Knowing if someone has Hepatitis B is important because it can help prevent the spread of the virus to others and allow for appropriate medical care and treatment. It is especially important for pregnant women to be tested, as they can pass the virus to their babies.
