The hepatitis B two-to-one test is a commonly used clinical test to detect serum markers of the hepatitis B virus in the blood. The two pairs of hemoglobin refer to the hepatitis B virus surface antigen (HBsAg) and hepatitis B virus surface antibody (HBsAb), and the hepatitis B virus e antigen (HBeAg) and hepatitis B virus e antibody (HBeAb). The half of the two pairs refers to the hepatitis B virus core antibody (HBcAb). Different combinations of permutations generally represent different situations: 1. All negative: This means that the person tested has neither a history of hepatitis B virus infection nor any existing infection. It is a vulnerable group of people who need to pay attention to protection in daily life and timely vaccination if necessary; 2, HBsAg and HBeAg positive: it means that there is hepatitis B virus infection in the body of the tested person, usually in the latent stage or early stage; 3, HBsAg, HBeAg, HBcAb positive: commonly known as the major three yang, representing the existence of hepatitis B virus infection in the body of the tested person and high infectiousness, in the acute or chronic stage. High, in the acute or chronic phase; 4, HBsAg, HBeAb, HBcAb positive: commonly known as the small triplet, representing the hepatitis B virus infection in the late or chronic phase; 5, HBsAb positive: indicates that the subject will have been infected with the hepatitis B virus, or vaccinated against hepatitis B, the body exists antibodies, you can further clarify the antibody strength, if there is a weakening, you can make up for it; 6. HBsAb, HBeAb, HBcAb positive: indicates that the subject’s infection is in the recovery stage or healed; 7. HBsAb, HBcAb positive: indicates that the subject’s infection is healed and has developed immunity; 8. HBcAb positive: this condition may indicate the existence of a history of hepatitis B virus infection, or at this stage there is a mild degree of chronic infection, or in the early recovery stage, or in the acute infection stage. or in the acute infection period.
