Test Code LAB868 Hepatitis C Antibody
Intended Use
Used to aid in the diagnosis of Hepatitis C. The serologic window between HCV infection and the detectability of specific antibodies varies from patient to patient.Seroconversions occur on average 7-8 weeks after the onset of infection. Anti-HCV is detectable in 50-70% of patients at the onset of clinical symptoms and later in the remaining patients. In patients with spontaneously resolving infection,anti-HCV may persist throughout life, or decrease slightly while remaining detectable or gradually disappear after several years. Anti-HCV persists indefinitely in patients who develop a chronic infection, although antibodies may become undetectable in cases of profound immunodepression.
