Interpretation of hepatitis B Test results

Blood tests are checked for Hepatitis B virus, and it is known that you have already done so, or this infection is recent. To check the virus, antigen, antibody, genetic material (DNA) is checked in the blood. If your doctor tells you that your result is normal or negative after the doctor’s check, this means that your body does not have any antigen, antibody, genetic material (DNA) related to hepatitis B.

If the result is positive, then the results of the investigation can be done in such a way – 

Hepatitis B (HBV)

Antigen associated with hepatitis B (HBV) virus, antibody, is present. After this it is detected that you have acute or chronic (long-term) infections.

Hepatitis B Surface Antigen (HBsAg) – These antigens are found in the body, when you have recently been infected, and active infections. If after 6 months this test is positive then it means that you have chronic infection and this transition can spread to others as well.

Hepatitis B Surface Antibody (HBsAb) – This antibody is found in the body when you have vaccinated HBV. It protects you from HBV infection throughout your life. If during the test it will be known that if you have both HBsAb antibody and HBsAg antigen present, then this means that you have an infection of HBV. But this is rarely seen.

Hepatitis B e-Antigen (HBeAg) – This antigen tells you that your body has a virus infection and it is in an active state.

HBV DNA Testing- If you have just transitioned, then your genetic material (DNA) of this virus will be present in your blood.

Hepatitis B core antibody (HBcAb) – These antibodies are found in the body, when you have been infected with this virus. But this test does not tell when the infection has happened to you.
Hepatitis B core antibody IgM (HBcAbIgM) – If you have had an infection within 6 months, then these antibodies are found in your body, and it is gradually increasing in the body.

Hepatitis B e-antibody (HBeAb) – present in this antibody in the body, indicates that you are not active HBV infection. You are less infectious, but still you can infect others.

Hepatitis D (HDV)

This test only shows that HDV has been infected. It does not provide any information about acute or chronic infection.
