Hepatitis C Antibody Test: What It Shows and What It Does Not

Quick answer: The hepatitis C antibody test looks for antibodies that form after exposure to the hepatitis C virus. A reactive result means you were exposed at some point. A follow up test shows whether the virus is still present.

About this test

The test detects antibodies to hepatitis C. Antibodies appear weeks to months after infection and can stay after the virus clears.

Why is it ordered?

  • Screening adults for hepatitis C.
  • A possible exposure.
  • Elevated liver tests on other blood work.

What results may show

  • A reactive result means past or current exposure and needs a follow up test for the virus.
  • A nonreactive result after the window period suggests no infection.

What this test may not show

  • It does not show whether the infection is active. A viral RNA test does.
  • A very recent infection may not be detected yet because antibodies take time to form.
  • It does not show liver damage.
  • It does not test for other infections.

How to prepare

  • No special preparation is needed.
