Hepatitis C Virus (HCV Antibody) IgG Test :
A blood test that detects IgG antibodies specific to the Hepatitis C virus (HCV). The presence of HCV IgG antibodies indicates past exposure to the virus, suggesting that the person has been infected with HCV at some point. However, it does not distinguish between a resolved infection (where the virus was cleared) or a current, ongoing infection. A positive IgG result is typically followed by further tests (like HCV RNA testing) to confirm whether the infection is active and to guide treatment decisions.
