| Factors To Be Tested | HBV Antigen or Antibody | Use |
| HBsAg | Hepatitis B surface antigen | Detection of acutely or chronically infected people; antigen used in hepatitis B vaccine |
| Anti-HBs | Antibody to HBsAg | Identification of people who have resolved infections with HBV; determination of immunity after immunization |
| HBeAg | Hepatitis B e antigen | Identification of infected people at increased risk of transmitting HBV |
| Anti-HBe | Antibody to HBeAg | Identification of infected people with lower risk of transmitting HBV |
| Anti-HBc | Antibody to HBcAga | Identification of people with acute, resolved, or chronic HBV infection (not present after immunization) |
| IgM anti-HBc | IgM antibody to HBcAg | Identification of people with acute or recent HBV infections (including HBsAg-negative people during the "window" phase of infection) |
HBcAg indicates hepatitis B core antigen; IgM, immunoglobulin M.
