Hepatitis B virus carriers can get health certificates. If the liver function is abnormal, HBVDNA is positive, the virus replication in the body is active and contagious, the patients with Big Three Yang will not get a health certificate. If the patient has normal liver function, normal DNA and no symptoms of hepatitis, he is a big three-positive virus carrier. However, you can only get a class B health certificate, and it is unlikely that FNA will turn negative, but you can take nucleoside drugs orally for antiviral treatment, which may have the opportunity to turn the big sun into a small sun.
