Blood tests are done to check for hepatitis C:
- EIA assay to detect hepatitis C antibody
- Hepatitis C RNA assays to measure virus levels (viral load)
Genetic testing is done to check for the hepatitis C genotype. Six genotypes exist. Test results can help your doctor better choose your treatment.
Most Americans have genotype 1 infection, which is the hardest to treat.
Genotypes 2 and 3 are also common, and respond better to treatment.
The following tests are done to identify and monitor liver damage from hepatitis C:
- Albumin level
- Liver function tests
- Prothrombin time
- Liver biopsy can show how much damage has been done to the liver.
