What should you know about PCR for hepatitis C?

Hepatitis C PCR is often considered after an initial blood test has found antibodies. Antibodies show that the immune system has encountered the virus; PCR looks for viral genetic material now. A detected result supports current infection, while a not-detected result may mean there is no detectable virus at the time of sampling. Your clinician considers the timing of exposure, previous treatment and the possibility that testing needs repeating. Hepatitis C can cause fatigue or no obvious symptoms, so how you feel cannot reliably predict the result.

Attend a GP consultation to review the reason for testing and any earlier results. Tell the clinician about previous hepatitis testing, treatment, blood exposures and medicines. Further assessment may include a liver function test and checks that help plan care. Do not share razors, toothbrushes or needles, and cover bleeding wounds until you have received personalised advice. Avoid donating blood while current infection is being assessed. Modern treatment decisions are individual, so wait for the full clinical review rather than interpreting one line on a report.

Seek urgent help for yellowing of the skin or eyes with severe illness, vomiting blood, black stools, confusion, fainting, severe abdominal swelling or difficulty staying awake. Contact a clinician promptly if you have ongoing fatigue, dark urine, pale stools, nausea or pain under the right ribs, especially after a possible exposure. Bring the report to appointments.

Ask whether the result is detected, whether viral quantity was measured, what other liver checks are needed, whether treatment is appropriate, and how to protect others while assessment continues. Confirm when repeat testing and follow-up will happen.
