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.
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.
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 positive. Both...
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.
19 lip 2020 · The HCV RNA PCR test can confirm whether you have the hepatitis C virus in your blood. Discover the types of tests, what the results mean, and more.
This assay has a result range of 15 to 100,000,000 IU/mL (1.18 log to 8.00 log IU/mL) for quantification of hepatitis C virus (HCV) RNA in serum. An "Undetected" result indicates that the HCV is absent in the patient's serum specimen.
19 gru 2023 · Nucleic acid test (NAT) to detect presence of HCV RNA (qualitative RNA test). NAT to detect levels of HCV RNA (quantitative RNA test). A reactive HCV antibody test result indicates a history of past or current HCV infection. A detectable HCV RNA test result indicates current infection.
