Diagnosis of Hepatitis B in Humans

Diagnosis of hepatitis B is established through a series of blood tests, namely antigen and antibody tests for hepatitis B virus, and blood tests to see liver function.

  1. There are three types of antigen and antibody tests for hepatitis B, namely:Hepatitis B surface antigen (HbsAg). This test is performed to assess the transmission of hepatitis B virus. Negative test results (-) means no hepatitis B virus in your blood. While positive test results (+) indicate that you have hepatitis B virus in the body and potentially spread this virus to others. However, this test can not distinguish whether the infection is occurring (acute) or has occurred in the past (chronic).
  2. Hepatitis B core antigen (HbcAg). This test is often done if your HbsAg results show positive results, because with this test can be seen whether the hepatitis B that you experience is acute or chronic. Positive HbcAg generally means you have chronic (long-term) hepatitis B, or it may mean you are recovering from acute hepatitis B.
  3. Hepatitis B surface antigen (anti-HbsAg) antibody. This test shows your immunity to hepatitis B virus. Your anti-HbsAg apabia is positive, it is likely that you will be protected from hepatitis B virus. A positive test result can mean you have been getting a hepatitis B vaccine or you have been in recovery from acute hepatitis B .

In addition to the above three tests, your doctor may recommend blood tests to see liver function. This liver function test will see if there is an increase in liver enzymes, indicating that your heart is working harder than usual, under pressure, or is being damaged.
