The Hepatitis C Virus (HCV) IgG Serum test is a specialized blood test that detects IgG antibodies produced by your body in response to a Hepatitis C infection. A positive result indicates that you have been exposed to the virus at some point, even if you do not currently have symptoms. A simple blood draw allows the lab to measure these antibodies accurately, giving your doctor critical insight into your infection history. This test is essential for identifying past or chronic infection, guiding further confirmatory testing, monitoring liver health, and helping your doctor plan timely, appropriate care.
