What should you know about a hepatitis B check-up?

The clinician may ask about vaccination, previous test results, pregnancy, household or sexual exposure, tattoos, piercings, injections and medicines. Symptoms can include fatigue, nausea, poor appetite, discomfort below the ribs, yellowing of the eyes or skin and dark urine, although some people have no symptoms. Fatigue is a possible feature of hepatitis B, not proof that hepatitis B is the cause.

Blood tests can show whether the virus or related markers are present and may help clarify whether infection is recent or ongoing. A liver function test provides information about liver irritation or how well the liver is working. Additional follow-up depends on the results.

Bring a list of medicines and supplements, vaccination records if available, and details of any possible exposure. Ask whether you need to fast before blood tests; do not assume that you do. Until results are discussed, avoid sharing razors, toothbrushes or needles, cover cuts, and use condoms. Close contacts can ask about testing and hepatitis B vaccination.

Arrange prompt medical advice after a possible recent exposure. Seek urgent care if yellowing, dark urine with worsening illness, persistent vomiting, severe abdominal pain, confusion or unusual drowsiness occurs. Emergency help is needed for collapse, severe bleeding or inability to stay awake.

Ask which hepatitis B markers will be checked, whether a liver function test is included, when results will be ready, and what happens if a result is positive or unclear. Ask when repeat monitoring is needed and whether your contacts should be vaccinated.
