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 or needles, or if you have unexplained liver concerns. It may also be used as part of a screening or monitoring plan for chronic liver conditions.
What to Expect Before the Test
No special preparation is needed. You’ll have a small needle inserted into your arm to draw blood. The process usually takes a few minutes. If you’re nervous, let your healthcare provider know—they can help make it more comfortable.
What the Test Results Mean
If antibodies are found, it means your body has recognized the hepatitis C virus at some point, but it doesn’t necessarily mean you’re currently infected. A positive result should be followed up with additional testing, such as HCV RNA testing, to check for active infection.
What Happens Next If Results Are Positive
A positive result triggers further evaluation, often including HCV RNA testing to confirm active infection. Your healthcare provider will discuss treatment options and next steps, such as liver function tests or counseling about hepatitis C management.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is critical for identifying past exposure to hepatitis C, which is essential for managing liver health. While antibodies indicate exposure, active infection requires further assessment. Early detection allows for timely intervention, which can prevent liver damage or chronic disease progression.
