15 sie 2019 · The quantitative HCV RNA test is checked before a patient starts treatment. For each patient, the result can be described as either a "high" viral load, which is usually >800,000 IU/L, or a "low" viral load, which is usually <800,000 IU/L.
A repeatedly reactive result is consistent with current HCV infection, or past HCV infection that has resolved, or biologic false positivity for HCV antibody. Test for HCV RNA to identify current infection. HCV antibody reactive, HCV RNA detected. Current HCV infection.
14 lip 2021 · After an acute HCV infection, HCV RNA could be detectable in serum within 2 weeks following exposure. On the other hand, anti-HCV could take about 8-12 weeks before results are...
Since 2013, the US Centers for Disease Control and Prevention (CDC) recommends that all specimens that are HCV antibody reactive should be tested using a NAT to detect HCV RNA in order to confirm current HCV infection.
The mainstay in diagnosing infection with HCV is to initially screen high risk groups for antibodies to HCV (anti-HCV). The inclusion of serum to cut-off ratio (S/CO) in recent guidelines is helpful in deciding the supplemental assay to be used to confirm initially reactive screening results.
A reflex test for serum specimens that are hepatitis C virus (HCV) antibody screen-reactive for diagnosis of chronic hepatitis C. This test is appropriate for diagnosis of acute hepatitis C in high-risk or immunosuppressed individuals who may be negative for HCV antibodies.
