Why This Test Is Done

Your healthcare provider may recommend this test if you have risk factors for hepatitis C, such as exposure to contaminated blood, long-term intravenous drug use, or exposure to HCV in a healthcare setting. It may also be used as part of a screening or diagnostic evaluation for liver disease or unexplained liver concerns.

What to Expect Before the Test

No special preparation is needed. You may have a blood sample drawn from a vein in your arm by a healthcare professional. The process is quick and typically causes only minor discomfort.

What the Test Results Mean

A positive result indicates the presence of HCV antibodies, suggesting past infection. A negative result means no detectable antibodies were found, but it does not definitively rule out current infection. Follow-up testing may be needed if risk factors are present.

Possible Side Effects

Most people experience only minor side effects, such as a slight bruise, swelling, or soreness at the injection site. Rarely, there may be a reaction to the blood draw, such as dizziness or fainting.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance

Short name

HCV IgG Antibody

Frequently asked questions

What does a positive result mean?
A positive result means your body has produced antibodies against hepatitis C, indicating past infection. However, it does not confirm whether you currently have active HCV. You may need additional testing to assess current infection status.
Can I get hepatitis C from this test?
No, this test involves only blood collection for analysis. The risk of transmitting hepatitis C through a blood draw is extremely low due to strict safety protocols and sterile procedures.
How often should I get this test?
The frequency depends on your risk factors. If you have no risk factors, routine testing is not typically recommended. If you have risk factors (e.g., past exposure, chronic liver disease), your healthcare provider may recommend periodic testing based on your medical history and needs.
