It can be prevented by using effective vaccines. Different tests are also performed to check whether a person is infected or not. The test for Hepatitis B is also well-known by HBV test. This test is done to check the presence of antibodies that are produced by the body in opposition to Hepatitis B infection. The test for the detection of antigen that is produced by Hepatitis B virus is also performed. The test that is performed to identify the viral DNA is the last category of HBV test.
Why is it required to undergo HBV Testing?
- There are two major kinds of Hepatitis B namely chronic Hepatitis B and acute Hepatitis B and tests are required to conclude if the patient is affected by any one of them.
- HBV Testing is carried out to decide the category or damage of Hepatitis B virus that is disturbing the patient

- HBV testing is required to conclude whether a person was exposed or infected with hepatitis B virus.
Types of HBV Testing: Firstly hepatitis B is diagnosed using a blood test. This test looks for certain antibodies and antigens.
- Hepatitis B surface antigen (HBsAg) - The purpose of this HBV Test is to determine the presence of protein on the surface of the virus. This test is helpful in identifying those people who are infected with Hepatitis B infection before any symptom appears. The function of this test is to identify that if a person is previously enduring the chronic type of Hepatitis B infection.
- Hepatitis B surface antibody (anti-HBs) – this test is performed for determining that the antibody that is formed in reaction to HBV surface antigen through treatment has recovered the acute form of Hepatitis B.This result verifies that if a person still desires for a vaccine or whether you are protected against Hepatitis B virus.
- Total anti-hepatitis B core (anti-HBc, IgM, and IgG) – the function of this test is to detect the IgG and IgM antibodies to hepatitis B core antigen. It means that it can determine whether a person is infected with chronic or acute hepatitis B infection.
When is it needed for a person to have these tests? Hepatitis B is that type of infection in which person feels some symptoms like feeling fatigue, fever, vomiting, and loss of appetite, nausea dark urine, abdominal pain, jaundice and joint pain.
