What is the HBsAg test or Hepatitis B Surface Antigen test?

The HBsAg test is done to determine hepatitis B surface antigens in your blood and is used to find whether you have a recent or long-standing infection from HBV. Hepatitis B Virus has proteins named antigens on its surface that cause a person’s immune system to make antibodies, and the Hepatitis B surface antigens can be found in blood within many weeks after the body is infected. They are considered the primary signs of a hepatitis B infection in an individual. 

HBV is known and is one of the five hepatitis viruses. The other four are hepatitis A, C, D, and E, and most all infections are caused by these five viruses. HBV spreads all through the blood, seminal fluid, and vaginal secretions and takes many months to develop symptoms after a person gets infected. The virus causes an infection in the liver, and in most cases, it ckear out in six months on its own. But the virus in some cases of adults and a few children do not go away, especially in newborns, and is called having a chronic infection. If left undiagnosed and untreated, it can lead to liver cell damage, scarring, cirrhosis, and even liver cancer. 

Why is the HBsAg test done?

A doctor does HBsAg test to determine the information about the current or past infection with HBV. A blood test identifies present hepatitis B infection, past exposure to the same, or immunity to the virus. The hepatitis B virus spreads through contact with body fluids, mainly by blood-to-blood contact but can also be transmitted through other body fluids. The infection can be acute or chronic, and acute hepatitis B is a short live infection. 

A person with this type of infection usually recovers entirely from it without treatment within a few weeks or six months. A small percentage of people with acute hepatitis B infection progress to have a long-term chronic infection that lasts for six months or more. If a person has chronic hepatitis B infection, they are more prone to developing severe complications like liver cancer, liver failure, and damage to the liver. The HBsAg test is done for many purposes:
