You can determine whether you are infected with the hepatitis B virus through tests such as hepatitis B two half-pair test and hepatitis B virus DNA quantification.
1. Hepatitis B half-pair test, through blood sampling, detection of serum markers, if the hepatitis B surface antigen is positive, suggesting infection with the hepatitis B virus.
2. Hepatitis B virus DNA, by drawing blood and testing serum hepatitis B virus DNA, to determine whether there is replication of hepatitis B virus in the body, if hepatitis B virus DNA is quantitatively positive or exceeds the standard detection value, it suggests that hepatitis B virus is infected.
In addition, if infected with hepatitis B virus, also need to check liver function, abdominal ultrasound, etc., if the liver function is abnormal, transaminase or bilirubin is elevated, to exclude other reasons, it means that there is hepatitis B, and need to be treated in time, if abdominal ultrasound suggests that the liver cirrhosis, it is more necessary to timely antiviral treatment.
