Understanding Hepatitis C: Symptoms, Signs, and Causes
Diagnosis and Testing for Hepatitis C. Diagnosing Hepatitis C typically involves blood tests to detect the presence of the virus and to assess liver function. The initial test, known as an antibody test, can determine whether a person has ever been exposed to the virus. If the test is positive, a follow-up test is required to confirm whether the infection is still active. Further tests, such as a liver biopsy or imaging studies, may be necessary to evaluate the extent of liver damage.
