What a positive HBsAg test means
A positive HBsAg means the hepatitis B virus is present. Many people carry it for years without symptoms. What matters is how active the virus is and whether the liver is being damaged.
Evaluation
- HBeAg, HBV DNA (viral load) and liver tests
- FibroScan to check for scarring
- Ultrasound and, where needed, liver cancer surveillance
Treatment and follow-up
Not everyone needs medicines — some people only need regular monitoring. When treatment is needed, modern oral antivirals are effective at suppressing the virus and protecting the liver. Family members should be tested and vaccinated.
