Anti-HCV Antibody, Qualitative (Serum/Plasma)
This test detects antibodies to the hepatitis C virus (HCV) in your blood. It helps determine if you’ve been exposed to the virus, even if you don’t yet have active infection.
["This test screens for past or potential hepatitis C exposure, not active infection."]

Why This Test Might Be Ordered
Your healthcare provider may recommend this test if you have risk factors for hepatitis C, such as a history of blood transfusions before 1992, intravenous drug use, or exposure to contaminated needles. It may also be used as part of routine screening for certain conditions or after potential exposure.
What to Expect Before the Test
No special preparation is needed. You’ll provide a blood sample, usually drawn from a vein in your arm. The test is quick and typically done in a clinic or lab setting.
What the Test Results Mean
A positive result means your body has produced antibodies against HCV, indicating past exposure. A negative result suggests no detectable antibodies, meaning you likely haven’t been exposed recently. This does not confirm or rule out active infection—additional tests are needed for that.
Next Steps After Testing
If your result is positive, your provider will likely order follow-up tests, such as HCV RNA testing, to check for active infection. If negative, they may monitor your risk factors or repeat the test if you have ongoing exposure concerns.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
This test is primarily used for screening and not for diagnosing active hepatitis C. Antibodies appear after exposure but may take weeks to months to develop. A positive antibody test alone cannot confirm current infection—it only indicates prior exposure or potential immunity.
A positive antibody test means your body has likely encountered the hepatitis C virus in the past, but it does not guarantee you are currently infected. You may need further testing, such as HCV RNA, to determine if the virus is still active in your system.
A negative antibody test means your body did not detect antibodies to HCV at this time. However, it’s possible you haven’t been exposed yet or the test was taken too early. If you have risk factors, your provider may recommend retesting or additional screening.
