Hepatitis B 1245 positive with normal liver function and negative DNA indicates that the infectiousness of hepatitis B virus is very low, but there is a small amount of hepatitis B virus in the patient’s body, and since the virus is less harmful to the patient’s liver, the patient’s liver function is not affected by the virus. Hepatitis B 1245 positive means that hepatitis B surface antigen, surface antibody, e antibody and core antibody are positive, and the result of this test also indicates that the patient is hepatitis B mini-tertiary, and hepatitis B mini-tertiary patients usually do not have active hepatitis B virus in their bodies. If the patient’s liver function is normal and DNA is negative, it means that the patient should be in the early stage of infection. Although it has little effect on the patient temporarily and the ability of spreading is low, but if it is not treated in time, it is very likely that the patient’s liver function will decline and lead to cirrhosis of the liver, and some patients will even develop into liver cancer. Patients need to pay attention to the presence of hepatitis B virus as long as it is detected in the body, and should take correct treatment measures under the guidance of the doctor in a timely manner, and the common method is medication, which can inhibit the development of the virus, such as entecavir, tenofovir, etc. During the period of medication, patients should also go for regular checkups and medical checkups. During the medication period, you should go to the hospital regularly to check your liver function and the change of viral vector.
