Hepatitis B 245 values are all high, which generally means that Hepatitis B 2 halves 2, 4 and 5 are positive. This result suggests that the patient has been infected with the hepatitis B virus in the past, and the virus has been cleared from the body, or he/she is in the recovery period of acute hepatitis B. Hepatitis B 2:5 is a commonly used clinical test for hepatitis B virus infection, which includes hepatitis B surface antigen and antibody, hepatitis B e antigen and antibody, and hepatitis B core antibody. High values of 2, 4 and 5 generally mean that the values of Hepatitis B surface antibody, Hepatitis B e antibody and Hepatitis B core antibody are out of the normal values, which means that they are positive. Positive values of the above three items are usually due to the fact that the patient has been infected with hepatitis B virus in the past, but the virus has been completely cleared under the action of autoimmune system, and the body has already produced antibodies against hepatitis B virus, so the probability of being infected with hepatitis B virus again is low. In addition to the above reasons, patients who have recently developed acute hepatitis B virus infection, after actively seeking medical treatment, will also indicate that the test results of hepatitis B two halves 2, 4, 5 positive. At this time, patients indicate that the number of hepatitis B virus in their bodies is decreasing, the activity is decreasing, and the condition is in the recovery period. However, if patients relax their vigilance because of this test result, and do not follow the doctor’s instructions to use medication, take less medication or omit to take medication, etc., it may lead to recurrence of the condition or even continue to deteriorate. Subsequently, it is still necessary to regularly review the hepatitis B half-pair test to rule out the possibility of hepatitis B surface antigen re-positive. To summarize, hepatitis B half 2, 4, 5 are high, patients do not need to worry too much, under the guidance of the physician regular rechecking of hepatitis B half can be.
