Hepatitis C Virus (HCV Antibody)

If your hepatitis C antibody test is positive, you’ll need a PCR (HCV RNA) test to confirm active infection. Doctors assess liver health (blood tests, imaging, fibrosis staging), check for co‑infections, and offer direct‑acting antiviral treatment that cures most people. You’ll receive counseling on transmission prevention, vaccinations for hepatitis A/B if needed, and follow‑up testing after treatment to confirm viral clearance.

Yes. Hepatitis C (HCV) can be serious: many infections become chronic, causing progressive liver inflammation that may lead to fibrosis, cirrhosis, liver failure, and hepatocellular carcinoma. It is often asymptomatic early, so testing is important. Highly effective antiviral treatments now cure most people, and early diagnosis greatly reduces long-term complications.

Normal HCV antibody result is "non‑reactive" (negative). Many lab assays use an index: negative is typically below the assay cutoff (commonly <0.9–1.0), an indeterminate/equivocal gray zone around 0.9–1.1, and reactive/positive at or above the cutoff (≈1.0 or >1.1 depending on the test). Reactive results require HCV RNA testing to confirm active infection.

Hepatitis C is screened with an anti‑HCV antibody test; a positive antibody requires HCV RNA PCR to confirm active infection. Quantitative RNA establishes viremia and guides treatment; genotyping (or sequencing) informs regimen choice. Baseline liver assessment includes liver function tests and fibrosis evaluation (blood scores, elastography or biopsy). Repeat RNA testing after therapy confirms sustained virologic response.

Hepatitis C is not literally 100% curable for every person, but modern direct‑acting antiviral (DAA) treatments cure over 95%–99% of people, usually after 8–12 weeks, shown by sustained virologic response (SVR12). Some with advanced liver disease, resistant virus, or prior treatment failures may need different regimens. Reinfection is possible, so prevention and follow‑up testing are important.

HCV negative usually means no hepatitis C infection was detected — this is good. However, tests can miss very recent infections during the “window period,” so negative results after recent exposure may warrant repeat testing or an HCV RNA test to detect early infection. If you have ongoing risk factors, discuss follow‑up testing with a healthcare provider.
