Hepatitis B Surface Antigen (HBsAg), also known as Australia antigen is present on the surface of the Hepatitis B virus (HBV). This test detects the presence of Hepatitis B Surface Antigen (HBsAg) in the blood. Several different forms of viruses exist. Some of them cause minor symptoms that are hard to notice and easy to address, while others may be more serious or infectious. Viruses typically enter and affect a particular part of the body, lowering its functioning and efficiency. The Hepatitis B virus is very infectious and usually attacks the liver. The Hepatitis B virus can be easily tested using a simple blood test that can be taken at any time during the day. A Hepatitis B panel test can help give information about past exposure to Hepatitis, identify current infection and reveal immunity to the virus. From a range of examinations, the HBsAg test shows if the Hepatitis infection currently exists in your body and if you run the risk of passing it to others. Other tests conducted as part of the Hepatitis panel include HBsAb, HBcAb and IgM. These tests can show whether immunity to Hepatitis has been built or if there have been past infections. The HBsAg test is used in the diagnosis of Hepatitis in cases where symptoms including pain, loss of appetite, discolouration of the skin, urine and stool or fatigue are experienced. Although difficult to ascertain, some of the risk factors that could cause Hepatitis includes passing or exchanging body fluids, blood and semen. While the HBsAg blood test is important when your doctor notices any of these symptoms, it may also be suggested if you have recently travelled to places where Hepatitis is common. Hepatitis B is the most common yet serious liver condition. Known as a silent epidemic, it is hard to know when you have been infected since there are no visible symptoms in the initial stages. Today, Hepatitis B can be easily diagnosed with the HBsAg blood test and treated quickly. Hepatitis B is widely prevalent in India, with a greater concentration in Arunachal Pradesh and the Andamans. There is a significant increase in the prevalence of the condition among tribal populations compared to non-tribal Indians. The most important reason for outbreaks is infection through unsterilized or inadequately sterilized syringes and needles. The case of the acute outbreak in Modasa, Gujarat, is a classic case in point. The overall rate of Hepatitis B in India stands between 3 and 4%.
