1(HBsAg- hepatitis B virus surface antigen) in the two halves of hepatitis B is a sign that the virus has been infected, and it does not reflect whether the virus replicates, the degree of replication and infectivity. 2(HBsAb- hepatitis B virus surface antibody) is the sign of neutralizing antibody and the main sign of recovery or drug resistance. Hepatitis B vaccination, if only this positive, should be regarded as a normal phenomenon after hepatitis B vaccination; 3(HBeAg- hepatitis B virus E antigen) is a sign of virus replication. Persistent positive for more than 3 months tends to be chronic; 4(HBeAb- hepatitis B virus E antibody) is the stop sign of virus replication. Virus replication is reduced, and its infectivity is weak, but it is not completely non-infectious; 5(HBcAb- hepatitis B virus core antibody) is a sign of being infected or being infected.
Liver function measurement
GPT: alanine aminotransferase (normal value
T.BiL: total bilirubin (5.1-19umol/l d.bil: direct bilirubin (0-5.1umol/l), which is an index to judge whether there is jaundice.
TP: total serum protein (60-80g/l), which may include albumin and globulin, namely albumin (35-55g/L), GLP (20-30g/L) and A/G (1.5-2.5: 1). The upside-down ratio indicates that the liver function is seriously damaged. Decreased albumin will produce ascites.
