The HBsAg (hepatitis B surface antigen) test is a test that is done as a way to detect hepatitis B. If the test result is positive, it means that the hepatitis B virus has been detected in your body

Hepatitis B is one of the most common he alth problems in Indonesia. Based on the research results of the Ministry of He alth in 2013, there were around 2,981,075 Indonesians suffering from hepatitis, with 21.8% or around 649,874 of them suffering from hepatitis B.

Hep B disease often goes undetected, because some sufferers do not feel any symptoms. However, there are some symptoms that can be experienced by people with hepatitis B, including:

  • Yellow skin and eyes
  • Loss of appetite
  • stomach pain
  • Fever
  • Prolonged tired
  • White stools
  • Urine is dark in color

To diagnose hepatitis B, the doctor will perform a physical examination, liver function tests, and hepatitis B serology including an HBsAg test through a blood sample. As a step for early detection and treatment, HBsAg testing for pregnant women and newborns is also important.

The Role of HBsAg Test in Detecting Hepatitis B

HBsAg is a protein found on the surface of the hepatitis B virus. A positive HBsAg test indicates that a person is infected with the hepatitis B virus and may infect other people with the virus.

However, this test cannot be the only benchmark for detecting hepatitis B. This is because a positive HBsAg test result can also occur within 18 days after a person receives the hepatitis B vaccine.

If needed, the doctor will perform additional tests to confirm hepatitis B infection, namely anti-HBc, anti-HBs and IgM anti-HBc tests. In addition to diagnosing hepatitis B, this series of tests can also determine the type of hepatitis B you have, namely acute or chronic.

Acute hepatitis

In acute hepatitis B, the test results will show:

  • HBsAg positive
  • Anti-HBc positive
  • IgM anti-HBc positive
  • Anti-HBs negative

Acute hepatitis B infection will usually occur in a short time, which is about 1-3 months. After hepatitis B infection occurs, the body can fully recover within a few months with the support of a good immune system.

If the body's immune system can't completely fight off the virus, this acute hepatitis can develop into chronic hepatitis B.

Chronic hepatitis

In chronic hepatitis B, the test results show:

  • HbsAg positive
  • Anti-HBc positive
  • IgM anti-HBc negative
  • Anti-HBs negative

If hepatitis B infection occurs for more than 6 months, then this condition is considered chronic hepatitis B. Symptoms of chronic hepatitis B are usually milder or asymptomatic and sometimes recur frequently.

Patients with chronic hepatitis B infection may suffer from this disease for the rest of their lives. If left untreated, this condition can lead to serious complications such as cirrhosis and liver cancer.

To get protection from hepatitis B, you need to get hepatitis B vaccination, live a he althy lifestyle, and avoid risky behaviors such as free sex and sharing needles.

In addition, regular medical check-ups with the doctor, including the HBsAg test, are an important step in early detection of hepatitis B.
