What should you know about the HCV hepatitis C virus?

The HCV hepatitis C virus can infect the liver, often without early symptoms, so testing is needed after a possible exposure. HCV is not confirmed by symptoms alone. Antibody testing can show that the immune system has encountered the virus, while a follow-up virus test checks for current infection.

Fatigue, nausea, appetite changes, or discomfort near the liver can occur, but many people have no clear warning signs. Persistent infection may cause inflammation and scarring in the liver. A normal-feeling day or a single liver function test cannot settle the question; the correct virus tests and clinical context are needed.

Arrange a GP consultation if you have had a possible blood exposure, a past positive antibody test, or unexplained liver-test changes. Share the date and type of exposure, previous results, pregnancy plans, and medicines. Until the result is clarified, avoid sharing items that may carry blood and do not donate blood. Treatment and monitoring are tailored to the confirmed result.

Get urgent help for confusion, extreme sleepiness, vomiting blood, black stools, marked abdominal swelling, or yellow skin with severe illness. Seek prompt advice after a significant blood exposure, particularly if you have worsening fatigue, abdominal pain, or vomiting.

Ask whether you need antibody and current-virus testing, whether a liver function test or other assessment is appropriate, and how results affect partners or household contacts. Check which medicines and supplements are safe, how follow-up will be arranged, and which changes should be reported quickly.
