In the results of hepatitis B five tests, the first and fifth positive items of hepatitis B can very clearly indicate that the organism is being infected with the hepatitis B virus. The first one, which is the significance of hepatitis B surface antigen positivity, is a marker of hepatitis B virus infection, indicating that the organism has been infected with hepatitis B virus, while the fifth one, which is the significance of hepatitis B core antibody positivity, indicates that the organism has been infected with or is being infected by hepatitis B. However, if the first and the fifth items are positive at the same time, it means that the body is infected with hepatitis B virus, and in this case, it is necessary to do liver function test and hepatitis B virus DNA content test as soon as possible, as well as imaging tests, such as ultrasound, CT and MRI to clarify the diagnosis, and active treatment.
