With the increase of people’s health awareness, medical checkups have become a trend. In medical checkups, the five hepatitis B tests have become an essential laboratory test. How should we interpret the various results of the five hepatitis B tests? Now we have summarized several combinations of patterns and clinical significance that often occur, and we hope to learn them together with you. The first item: HBsAg Hepatitis B surface antigen. The second item: HBsAb Hepatitis B surface antibody. The third item: HBeAg Hepatitis B e antigen. The fourth item: HBeAb Hepatitis B e antibody. Fifth: HBcAb Hepatitis B core antibody. 1, – – – – -, all five items are negative, indicating normal. But there is no antibody, no immunity, you can go to the immunization station to inject hepatitis B vaccine. 2, – + – – -, the second positive item, indicating that there are antibodies and immunity. One kind of antibody is produced by infection, and the other is produced by vaccination. 3, + – + – – +, one, three, five positive, for “major three yang”. (1) acute or chronic hepatitis B active; (2) hepatitis B virus replication active, highly infectious. 4, + – – + +, one, four, five positive, for “small three yang”. It means that the virus replication is slow, the infectiousness is weak, and it is easy to become cancerous in the long term. 5.+ – – – +, one or five positive, “small two-positive”. This indicates moderate viral replication, recovery from acute hepatitis B or previous infection, and weak infectiousness. Look for elevated ALT in the liver function. If elevated for acute hepatitis B; if normal, ask if there are clinical symptoms, if there are no symptoms for carriers, if there are symptoms for chronic hepatitis B. 6, + – – – -, the first positive, for acute HBV infection early. There is viral replication, infectious. If it lasts for 6 months for chronic hepatitis B virus carriers. 7, – + – – + -, two or four positive, for hepatitis B recovery period, has produced antibodies, low infectious. 8, – + – + +, two-four-five positive: (1) previous infection (2) recovery period of infection, has produced antibodies, immunity. 9, – – – + +, four or five positive: (1) hepatitis B carriers (2) recovery period or recent infection, weak infectivity, weak viral replication. 10, – – – – +, fifth positive: (1) if IgG positive, previous infection, now recovered, no infectious (2) if IgM positive, current infection, viral replication, infectious (3) if IgG, IgM are positive, chronic Hepatitis B or virus carrier, has produced antibodies, has some immunity.
