HCV antibody testing is the first step in diagnosing Hepatitis C infection.

The CLIA method provides high sensitivity and specificity compared to conventional assays.

Clinical uses include:

Screening for Hepatitis C infection in blood donors and patients.

Diagnosing acute or chronic HCV infection.

Monitoring infectivity and disease progression.

Supporting evaluation before antiviral therapy.

A positive antibody test indicates exposure to HCV, but confirmatory tests (HCV RNA PCR) are required to detect active infection.

Analyte: Anti‑HCV antibodies in serum/plasma.

Normal Result: Negative (no antibodies detected).

Abnormal Findings:

Positive HCV antibody: Indicates past or current HCV infection.

Confirmatory testing (HCV RNA PCR): Required to establish active infection.

Clinical Use:

Provides a sensitive screening tool for HCV infection.

Helps prevent transmission via blood transfusion.

Supports monitoring and management of Hepatitis C patients.
