What this test measures
The hepatitis C antibody rapid test is an immunochromatographic assay that detects anti-HCV in serum, plasma or whole blood within 15–20 minutes. It detects the same antibody as lab ELISA/CLIA anti-HCV.
A reactive result means past or current HCV exposure. It does not distinguish active infection from cleared (spontaneous or treated) infection — that requires HCV RNA quantitative PCR.
Why it matters
India has an estimated 6–11 million people with chronic HCV. With sofosbuvir-based direct-acting antiviral (DAA) regimens, HCV is now curable in 8–12 weeks with > 95% success — and NACO India provides treatment free under the National Viral Hepatitis Control Programme.
The rapid test is widely used in outreach camps, dialysis units, prison and rehab settings, and pre-operative work. Any reactive rapid test triggers HCV RNA quantitative and genotype testing for treatment planning. WHO and NACO recommend HCV screening for high-risk groups: blood-transfusion recipients before 2001, IV drug users, dialysis patients, HIV-positive individuals, and people with persistently raised SGPT.
How to prepare
No fasting required. The test uses serum, plasma or whole blood (finger-prick). Mention any transfusion history, tattoos, dialysis, or known HCV contact.
Markers & reference ranges
Reference ranges below are typical adult values. Your lab's reported range may differ slightly based on the assay platform and patient demographics — always read your report against the range printed on it.
| Marker | Normal range | If low | If high |
|---|---|---|---|
| Anti-HCV (Rapid) (Reactive / Non-reactive)[1][2] | Non-reactive (Negative) | Non-reactive — no detectable HCV antibody. Window period is 4–10 weeks; if recent high-risk exposure, repeat at 12 weeks. HCV RNA can detect infection earlier. | Reactive — past or current HCV exposure. HCV RNA quantitative is mandatory to distinguish active (treatable) from cleared infection. |
Rapid HCV vs lab ELISA/CLIA
| Feature | Rapid card | ELISA / CLIA |
|---|---|---|
| Turnaround | 15–20 minutes | 4–24 hours |
| Sample | Finger-prick or serum | Serum |
| Sensitivity | ~95–98% | >99% |
| Specificity | ~98% | >99.5% |
| Confirmation needed | Yes — HCV RNA mandatory | Yes — HCV RNA mandatory |
| Use case | Camp, OPD, dialysis screening | Confirmation, blood-bank |
Frequently asked questions
My HCV rapid is positive. Am I infected?
A positive rapid test means past exposure. About 20–30% of people clear HCV spontaneously. HCV RNA quantitative is mandatory to confirm active infection.
Can hepatitis C be cured?
Yes. Direct-acting antiviral (DAA) therapy cures over 95% of patients in 8–12 weeks. India produces generic sofosbuvir-based combinations at low cost, and NACO provides free treatment under the National Viral Hepatitis Control Programme.
Will my rapid HCV become negative after cure?
No. Anti-HCV stays positive for life regardless of cure. Only HCV RNA turns undetectable after successful treatment.
How long after exposure does the rapid test turn positive?
Anti-HCV appears 4–10 weeks after exposure. If you suspect recent exposure and the rapid test is negative, repeat at 12 weeks, or do HCV RNA earlier.
Is the rapid HCV test acceptable for blood donation?
No. Indian blood-banking rules require ELISA/CLIA or NAT testing for donor screening. Rapid tests are for clinical triage.
Why are dialysis patients screened so often?
Long-term haemodialysis carries a small ongoing risk of HCV exposure through shared equipment if infection control is not strict. Indian and international guidelines recommend periodic HCV screening for dialysis patients.
Can hepatitis C be transmitted sexually?
HCV is mainly blood-borne. Sexual transmission is rare in monogamous heterosexual couples but increases with HIV co-infection, sexual practices that involve blood contact, and multiple partners.
