What should you know about PCR testing for hepatitis C?

A detected result means hepatitis C virus genetic material was found in the sample. It supports current infection, but the result should be interpreted with your symptoms, medical history and other blood tests. A not-detected result means the test did not find viral genetic material at that time. Testing soon after exposure or technical issues with a sample can affect interpretation, so a clinician may recommend repeat testing when the timing makes that appropriate. A PCR result does not by itself describe liver damage or confirm how long infection has been present. A Liver Function Test can provide different information about how the liver is working.

Take the report to a clinician who can match it with any earlier hepatitis C antibody test and decide whether further assessment is needed. Do not share razors, toothbrushes or needles, and avoid donating blood until you have received clear medical advice. If infection is confirmed, ask about treatment and ways to protect others from blood exposure. A GP Consultation can help organise testing, explain the report and arrange referral when needed. You can read more about Hepatitis C for broader information.

Arrange medical review promptly if a result is detected, if you have yellowing of the skin or eyes, dark urine, marked tiredness, abdominal swelling or unusual bleeding. Seek urgent help for confusion, severe vomiting, fainting or sudden severe abdominal pain. Fatigue alone has many possible causes, so it should be considered alongside the test result rather than used to diagnose hepatitis C.

Ask whether the result is detected or not detected, whether the sample timing matters, which liver tests are needed, and whether anyone else should be tested after a possible blood exposure.
