Hepatitis B core antibody 33.78 S/CO is not normal. A Hepatitis B Virus Core Antibody test result of less than 1.0 S/CO is negative and is normal. If it is greater than 1.0 S/CO, it is positive. Hepatitis B Virus Core Antibody 33.78 S/CO is abnormal, indicating that the subject is or has been infected with the Hepatitis B virus. Hepatitis B virus core antibody test needs to be combined with other indicators of hepatitis B five comprehensive diagnosis, analyzing hepatitis B virus core antibody alone is usually of little significance, hepatitis B surface antigen, hepatitis B e antigen and hepatitis B core antibody are positive, suggesting that the patient is hepatitis B “triple positive”; if hepatitis B surface antigen, hepatitis B e antibody and hepatitis B core antibody are positive, suggesting that the patient is hepatitis B “triple positive”. If Hepatitis B Surface Antigen, Hepatitis B e Antibody and Hepatitis B Core Antibody are positive at the same time, it suggests that the patient has Hepatitis B “Minor Triple Yang”. Hepatitis B core antibody 33.78S/CO patients need to further improve the relevant examination for definite diagnosis.
