What This Test Measures

The test detects specific antibodies (IgG) produced by your immune system in response to hepatitis C virus exposure. These antibodies are a sign that your body has encountered the virus, though they may not always indicate an active infection.

Why It’s Ordered

Your healthcare provider may order this test if you have risk factors for hepatitis C (e.g., exposure to contaminated blood, long-term organ transplant, or intravenous drug use) or if you have unexplained liver concerns.

Preparation

No special preparation is needed. A blood sample will be drawn from a vein in your arm. You may feel slight discomfort, but it should be brief.

What to Expect

The blood sample is processed to detect IgG antibodies using an immunoassay method. Results are typically available within 1–3 business days.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

A positive result means your body has likely been exposed to hepatitis C virus at some point, but it does not confirm an active infection. A follow-up test (e.g., HCV RNA) may be needed to assess current viral activity. A negative result suggests no past or current exposure to the virus.

Short name

HCV IgG

Frequently asked questions

What does a positive result mean?
A positive HCV IgG test indicates your immune system has encountered the hepatitis C virus, but it does not always mean you have an active infection. You may need further testing to check for current viral levels.
Can this test tell me if I have active hepatitis C?
No, this test alone cannot confirm an active infection. If you have risk factors or symptoms, your doctor may order additional tests (like HCV RNA) to check for ongoing virus presence.
How long does it take to get results?
Results are usually available within 1–3 business days after the lab processes your sample.
