Why This Test Might Be Ordered
Your healthcare provider may recommend this test if you have risk factors for hepatitis C, such as exposure to contaminated blood (e.g., through sharing needles, receiving a blood transfusion before 1992, or having a blood disorder). It may also be used as part of a screening or monitoring process for chronic liver conditions.
What to Expect Before the Test
No special preparation is needed. You may have a small needle inserted into a vein in your arm to draw blood. The process usually takes a few minutes. If you’re nervous, let your provider know—they can offer ways to make it more comfortable.
What the Test Results Mean
A positive result means your body has produced antibodies to HCV, suggesting past or current infection. A negative result means no detectable antibodies were found, indicating no current infection. This test alone cannot confirm active hepatitis C; further testing (like HCV RNA) may be needed for diagnosis.
Common Risks and Considerations
The most common risk is a mild bruise or soreness at the needle site. Rarely, there may be a reaction to the blood draw, such as dizziness or fainting. If you’re pregnant, have a bleeding disorder, or take blood thinners, let your provider know before the test.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
This test is critical for identifying past or ongoing hepatitis C infection, which can lead to chronic liver disease, cirrhosis, or liver cancer if untreated. Early detection allows for timely treatment and management to protect liver health.
Can I get hepatitis C from this test? No, hepatitis C is spread through blood and cannot be transmitted through routine blood draws or testing.
How often should I get this test if I have hepatitis C? If you have chronic hepatitis C, your provider may recommend regular monitoring (e.g., every 6–12 months) to check liver function and response to treatment.
