Which test indicates exposure to Hepatitis C?

• A. HCV antibody
• B. HCV RNA
• C. HBsAg
• D. HCV genotype

Answer: (A)

Detecting exposure to Hepatitis C is shown by the HCV antibody test, which looks for antibodies the body makes in response to the virus. A positive antibody result means the person has been exposed at some point, which could indicate past infection or ongoing chronic infection. To know if the infection is currently active, you test for HCV RNA; a positive RNA result confirms active viral replication, while a negative RNA with positive antibodies suggests past exposure with clearance. The other options aren’t about exposure: HCV genotype identifies the virus type for treatment decisions, and HBsAg indicates Hepatitis B infection.
