When a person is infected with HCV, the immune system produces antibodies against the virus. It usually takes the immune system a few weeks to develop enough antibodies to be detected by an antibody test. A person who has been recently infected with HCV may be in the window period – the time it takes between initial infection and the development of antibodies. The average time it takes for people to develop HCV antibodies is 2 months, but can take as long as 6 months; however, this is uncommon.
In people with a compromised immune system (organ transplant recipients and those who are HIV-positive) the body might not be able to develop enough antibodies to be detected by a test. Studies have found that anywhere between 8 and 10% of people coinfected with HIV and hepatitis C do not develop HCV antibodies. For this reason, it is recommended that persons with HIV who have a known risk factor for HCV, but who test antibody negative, get tested for HCV RNA (viral load test).
The most common type of HCV antibody test is the enzyme immunoassay (EIA and Elisa) – (manufacturers–Abbott, Bio-Rad, Innogenetics, Ortho). In populations with a high risk for acquiring HCV, the accuracy of these tests is up to about 99%. The HCV antibody tests are very sensitive so rarely will they be false-negative unless the person is in the window period.
