What should you know about a hepatitis B serology test?

The laboratory may report surface antigen, surface antibody, and core antibody. Surface antigen can indicate that hepatitis B material is present now. Surface antibody can indicate protection after vaccination or recovery. Core antibody can indicate past contact with the virus. The combination matters: a single line on the report cannot reliably establish the whole picture. Your clinician may consider the timing of an exposure, vaccination history, symptoms, and other blood tests when interpreting it.

The test does not measure liver function directly and cannot alone decide whether antiviral treatment is required. A Liver Function Test may be added. Hepatitis B may have no noticeable symptoms, but Fatigue, nausea, or Dark Urine can accompany illness.

Keep the laboratory report and review it with a healthcare professional rather than interpreting abbreviations on your own. If the pattern suggests current infection or recent exposure, ask about repeat testing, liver assessment, and testing for partners or household contacts. Until advice is given, avoid sharing personal items that may have blood on them and use barrier protection during sex. People without immunity can ask about Hepatitis B Vaccination.

Contact a clinician promptly after a result suggesting current infection, after a recent exposure, or during pregnancy. Go to urgent care for jaundice, confusion, severe vomiting, increasing abdominal swelling, unusual bleeding, or extreme drowsiness. These warning signs require assessment and should not wait for a routine appointment.

Ask which markers were included, whether the pattern indicates immunity or infection, whether timing could make the result inconclusive, and whether you need a Liver Function Test or repeat sample. Ask what your partner and household contacts should do, including whether Hepatitis B Vaccination is suitable.
