The result combinations of the five-item hepatitis B report card are diverse. The following are several common results and their clinical significance:

| HBsAg(+), HBsAb(-), HBeAg(+), HBeAb(-), HBcAb(+) | Acute or chronic hepatitis B infection with active viral replication |
| HBsAg(+), HBsAb(-), HBeAg(-), HBeAb(+), HBcAb(+) | Hepatitis B virus infection, weakened virus replication |
| HBsAg(-), HBsAb(-), HBeAg(-), HBeAb(-), HBcAb(+) | Previously infected with hepatitis B virus and recovered |
| HBsAg(-), HBsAb(-), HBeAg(-), HBeAb(-), HBcAb(-) | Not infected with hepatitis B virus and have no immunity |
3. Precautions for five hepatitis B tests

2.Check frequency:It is recommended that healthy people should be checked every 1-2 years; hepatitis B virus carriers or high-risk groups should be checked every 3-6 months.
3.Interpretation of results:The five results of hepatitis B need to be comprehensively judged in conjunction with other tests such as liver function and HBV-DNA. It is recommended to consult a professional doctor.
4. Frequently asked questions about five hepatitis B tests
Q1: What does hepatitis B surface antibody positivity mean?
A positive hepatitis B surface antibody indicates the presence of protective antibodies in the body, which may be due to immunity after vaccination or recovery from hepatitis B virus infection.
Q2: Does hepatitis B core antibody positivity require treatment?
Simple hepatitis B core antibody positivity usually does not require treatment, but it needs to be combined with other indicators to determine whether it is latent hepatitis B infection.
Q3: Can the five hepatitis B tests be used to determine infectivity?
The five hepatitis B tests can initially determine the infectivity, but the accurate judgment needs to be combined with the HBV-DNA test results.
5. How to prevent hepatitis B virus infection?
1.Get vaccinated:Hepatitis B vaccine is the most effective way to prevent hepatitis B. It is recommended that newborns be vaccinated within 24 hours after birth.
2.Avoid high-risk behaviors:Such as unclean injections, unprotected sex, etc.
3.Regular inspection:High-risk groups should undergo five hepatitis B examinations and liver function tests regularly.
Through the interpretation of this article, I believe you will have a clearer understanding of the five-item hepatitis B report card. If the test results are abnormal, please seek medical treatment promptly and follow the doctor's instructions for further examination and treatment.
