| Check items | English abbreviation | clinical significance |
|---|---|---|
| Hepatitis B surface antigen | HBsAg | Positive indicates infection with hepatitis B virus |

| result combination | clinical significance |
|---|---|
| HBsAg(+), HBeAg(+), HBcAb(+) | "Big three positives", the virus replicates actively and is highly contagious |
| HBsAg(+), HBeAb(+), HBcAb(+) | "Little three positives", virus replication is weakened and infectivity is reduced |
| HBsAb(+) | Immunity acquired after successful vaccination or recovery |
| All negative | Not infected with hepatitis B virus and have not developed immunity |
