Drinking white vinegar for a medical exam does not actually affect the detection of the hepatitis B virus, which is still detectable. Hepatitis B is an infectious disease characterized by liver damage caused by infection with the hepatitis B virus. Once infected, the hepatitis B virus is not affected by differences in diet. As long as the hepatitis B virus is not completely cured, the hepatitis B virus will not be completely negative, and drinking white vinegar for medical examination will not affect the detection of the hepatitis B virus in hepatitis B patients. In addition, patients with hepatitis B still need to actively cooperate with the doctor’s treatment, and go to the hospital regularly for review, so as to prevent it from transforming into cirrhosis of the liver or liver cancer and other more serious diseases.
