The five hepatitis B tests are currently used as a serological test for testing hepatitis B virus infection in domestic hospitals. The price of the test varies depending on the cost of the test method and the region where it is performed, and there is no clear price tag yet, generally ranging from$40-240. The five tests for hepatitis B are basic tests to determine the presence or absence of hepatitis B infection in the human body, through which the presence and replication of the hepatitis B virus can be understood indirectly. The hepatitis B five items mainly include five indicators, namely hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs), hepatitis B e antigen (HBeAg) and hepatitis B e antibody (anti-HBe), hepatitis B core antibody (anti-HBc). HBsAg is a sign of infection with the virus, but does not reflect the presence or absence of virus replication, the degree of replication, the strength of infectivity; HBsAb is a protective antibody. HBeAg is a sign of virus replication; HBeAb is a sign that virus replication has stopped or decreased, and is less infectious, but does not mean absolutely no infectiousness; HBcAb is a sign that the body has been infected or is being infected. Due to the different origins, the price of hepatitis B five also varies. The cost of domestic hepatitis B five tests is generally around 35-70 yuan, because its function is mainly a qualitative test, which can only show negative and positive, and is used for medical checkups or primary screening tests for hepatitis B. The imported hepatitis B five is a quantitative test that can show the value of each index, so the test cost is higher, generally around 240 yuan. In conclusion, the price of hepatitis B five is not fixed and is related to its origin and the test method, and the doctor will choose different indicators according to the patient’s needs.
