What This Test Measures
The test looks for antibodies produced by your immune system in response to the hepatitis C virus. Antibodies are proteins your body makes to fight infections. If you’ve been exposed to HCV, your immune system may produce these antibodies, even if you’re not currently infected. This test is often used as an initial screening step to check for past or recent exposure.
Why It’s Done
Doctors may recommend this test if you have risk factors for hepatitis C, such as a history of blood transfusions before 1992, needle exposure, or chronic liver issues. It can also be part of routine screening for certain populations at higher risk.
What to Expect
The test involves drawing blood from a vein, usually in your arm. You may feel a slight pinch, but it’s quick and painless. No special preparation is needed, though you should avoid alcohol for 24 hours before the test if advised by your doctor.
Next Steps If Results Are Abnormal
If your screening test is positive, your doctor will likely order additional tests, such as a confirmatory antibody test or viral load test, to determine if you have an active infection. These follow-up tests help guide treatment decisions.
