If a qualitative RNA test is positive (detected), then it is confirmed that the patient has chronic hepatitis C. If the assay DID NOT DETECT the virus, the test result will be reported as "Not Detected" If the assay DETECTED the presence of the virus but was not able to accurately quantify the number of copies, the test result will be reported as "< 10 Detected".

Order HCVQN / Hepatitis C Virus (HCV) RNA Detection and Quantification by Real-Time Reverse Transcription-PCR (RT-PCR). If the viral load is just at or above this LOD, but less than 15 IU/mL, the assay can determine that HCV RNA is present but cannot provide a reliable quantitative result. Both have a high sensitivity (based on the lower limit for detecting HCV RNA) and a great dynamic range and were standardized using the second WHO panel.
