What should you know about a positive hepatitis B result?

Hepatitis B testing uses different markers. A positive result may indicate current infection, past exposure, or immunity from vaccination, depending on the marker and the rest of the panel. It is not enough to infer how long the infection has been present or how much the liver is affected. Your clinician may review liver enzymes, viral activity tests, symptoms, and previous vaccination records. People with hepatitis B can feel completely well, while others develop [Fatigue](/symptoms/fatigue/) or [Dark Urine](/symptoms/dark-urine/).

Request the full report and ask which marker was positive. Arrange follow-up rather than relying on a single line in a portal. A [Liver Function Test](/treatments/diagnostics-and-screening/liver-function-test/) can help assess the liver, while other tests clarify whether the virus is active. Until your status is explained, avoid sharing razors, toothbrushes, or needles and use protection during sex. Tell close contacts to ask a clinician about testing and [Hepatitis B Vaccination](/treatments/preventive-care-and-vaccination/hepatitis-b-vaccination/).

Book medical review soon after a positive result, even if you have no symptoms. Seek urgent care for yellowing of the eyes or skin, severe abdominal pain, confusion, repeated vomiting, unusual bleeding, or rapidly worsening weakness. A positive test needs interpretation; it does not by itself predict severe illness.

Ask which marker is positive, whether you need confirmatory or repeat testing, how your liver is functioning, and whether treatment or monitoring is recommended. Ask when partners or household members should be tested or vaccinated.
