Why This Test Matters
Hepatitis C is a bloodborne virus that can cause liver damage over time. This test checks for antibodies that your immune system produces after exposure, which may indicate past infection. It’s often used alongside other tests to diagnose or monitor Hepatitis C.
How the Test Works
Your blood sample is tested using an immunoassay method to detect specific antibodies against Hepatitis C. If antibodies are found, it suggests your body has encountered the virus, though this doesn’t always mean you’re currently infected.
What to Expect Before the Test
No special preparation is needed. You may have a small needle inserted to draw blood from a vein in your arm. If you’re nervous, let your healthcare provider know—they can help make it more comfortable.
What the Results Mean
Positive results mean your blood contains antibodies to Hepatitis C, which could mean you’ve been infected at some point. Negative results mean no detectable antibodies were found, but this doesn’t rule out past exposure. Follow-up testing may be needed to confirm or clarify results.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
This test is critical for diagnosing Hepatitis C, which can lead to chronic liver disease if untreated. Early detection allows for treatment options that can help manage the virus and protect liver health. It’s also used in screening for those at higher risk of infection.
What if my test result is positive? If your test is positive, your healthcare provider will likely order additional tests to confirm the diagnosis and determine if you’re currently infected. They may also check liver function and recommend treatment options.
Can I take medications before this test? You can take your usual medications as directed, but let your healthcare provider know if you’re on any blood thinners or other medications that might affect blood tests.
