Hepatitis C Virus Antibody Screening (Serum/Plasma)

Why This Test Matters

Hepatitis C is a bloodborne virus that can cause long-term liver damage if not treated. Antibodies to HCV appear in your blood shortly after infection, often before you notice symptoms like fatigue, abdominal pain, or jaundice. This screening test is the first step in identifying potential exposure, guiding further testing (like HCV RNA), and planning care if needed.

What to Expect Before the Test

You’ll have a small needle inserted into your arm to draw blood. It usually takes about 5 minutes. You may feel a brief pinch, but most people tolerate it well. No special preparation is needed, but tell your provider if you’re on blood-thinning medication or have a bleeding disorder.

What the Test Results Mean

A positive result means your blood contains antibodies to HCV, suggesting past or current infection. A negative result means no detectable antibodies were found at this time. Follow-up testing (like HCV RNA) may be needed to confirm active infection or rule it out. Results are not diagnostic alone—they’re part of a broader evaluation.

Next Steps and Follow-Up

If your screening test is positive, your healthcare provider will likely order additional tests (e.g., HCV RNA) to confirm infection and determine its stage. Treatment options exist to clear the virus and protect your liver. If negative, repeat testing may be recommended if you’ve had risk factors (e.g., blood transfusions before 1992, needle use, or close contact with an infected person).
