Quick Answer
Hepatitis C screening is a blood test that looks for antibodies to the hepatitis C virus (HCV) or the virus's genetic material. It identifies past or current infection, often before symptoms appear. The CDC recommends a one-time screen for all adults aged 18 and older, and periodic testing for people at higher risk.
- Hepatitis C is a bloodborne virus – screening is different from hepatitis A or B screening.
- The first test detects HCV antibodies; a positive result needs a follow-up RNA test.
- Antibodies typically appear 8–12 weeks after exposure – this is called the window period.
- A negative antibody result usually means no infection, but re-testing may be needed after recent exposure.
- Screening can be done at a clinic, doctor's office, or with an at-home test kit.
The Short Version, Structured
Hepatitis C often causes no symptoms for years while silently damaging the liver. Screening is the only way to know if you have the virus, especially since early infection is usually symptom-free. The hepatitis C virus spreads through contact with infected blood, often through shared needles or medical equipment, and less commonly through sexual contact. Unlike hepatitis A (fecal-oral) or hepatitis B (blood and sexual), hepatitis C does not have a vaccine, making screening a key tool for early detection and treatment.
