What does a hepatitis C core antibody result mean?

The core antibody is made by the immune system after exposure to hepatitis C. It can remain detectable after the virus has cleared, whether that happened naturally or after treatment. A negative result makes previous exposure less likely, although timing and immune response affect interpretation.

To find out whether virus is currently present, a clinician may request an RNA or other current-virus test. Liver blood tests can provide information about liver inflammation, but a normal result does not settle the antibody question. See [Hepatitis C](/conditions/hepatitis-c/) for condition information.

Take the report to a clinician who can interpret it alongside your exposure history, symptoms, immune status, and any previous results. If the antibody is positive, ask whether current-virus testing has been completed or is still needed. Until the result is clarified, avoid sharing razors, toothbrushes, needles, or equipment that may carry blood. A [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) can coordinate follow-up. A [Liver Function Test](/treatments/diagnostics-and-screening/liver-function-test/) may be included as part of the assessment.

Arrange follow-up soon for a positive or unclear result, even if you feel well. Seek urgent help for yellow skin or eyes, confusion, marked drowsiness, severe abdominal swelling, repeated vomiting, or bleeding that is difficult to stop. Fatigue can occur with hepatitis C but is not specific; read about [Fatigue](/symptoms/fatigue/).

Ask whether the result is positive, negative, or indeterminate; whether a current-virus test is needed; and whether the laboratory has compared it with earlier results. Ask how to protect others from blood contact and whether liver assessment or specialist review is appropriate.
