Turnaround times
The quoted turnaround time is from sample receipt in the laboratory, to results authorisation in the Laboratory Information Management system. The times do not include transport of specimen to the laboratory or the administrative process to print and post/email reports. Service users must allow for transport and reporting time when ordering tests.
Clinical background:
Screening test for hepatitis C virus infection. This is a serological assay used to detect IgG antibodies to hepatitis C virus (HCV). HCV antibodies may take up to 3 months to develop after infection, so repeat testing is required if the patient has had potential recent exposure. HCV antibody testing may also not be reliable in immunocompromised individuals. HCV PCR testing is required to differentiate active hepatitis C infection from past, cleared infection in antibody positive patients.
