HCV RNA Quantitation By PCR
Hepatitis C RNA quantitation, HCV viral load, HCV Quantitative, HCV Quantitation, Hep C, Hepatitis C Virus, Quantitative by PCR , EPIC: LAB6403, SOFT: IQHCG
This test is not intended for use as a screening test for the presence of HCV in blood or blood products.
Specimen Collection Criteria
Collect: Serum OR Plasma.
- Serum: One Gold-top SST or plain Red-top tube.
- Plasma: One Lavender-top EDTA tube.
- Minimum volume and pediatric minimum (single test with no repeat): 650 mcL (0.650 mL) serum or plasma.
- Separate specimens must be submitted when multiple tests are ordered.
Physician Office/Drawsite Specimen Preparation
Centrifuge to separate serum or plasma from cells within 24 hours of collection. Transfer serum or plasma to a plastic transport tube and refrigerate (2-8°C or 36-46°F). A centrifuged SST tube is also acceptable at refrigeration temperature.
Preparation for Courier Transport
Transport: Serum or plasma, or centrifuged SST tube, refrigerated (2-8°C or 36-46°F). (Min: 1.1 mL)
- Specimens not centrifuged with the serum or plasma separated within 24 hours of collection.
- Specimens collected in Green-top heparin tubes or White-top PPT tubes.
- Specimens not maintained refrigerated following separation.
- Specimens exposed to repeated freeze/thaw cycles.
- Unlabeled tubes.
Once a week.
Results available within 7 days.
HCV RNA not detected. The limit of detection is 15 IU/mL.
Reportable range is 15 - 100,000,000 IU/mL. Results exceeding 100,000,000 will not be diluted, and will be reported as greater than 100,000,000 IU/mL.
Quantitative real-time polymerase chain reaction (qPCR)-Roche COBAS® Ampliprep/COBAS® TaqMan® HCV Test, v2.0 (FDA Approved).
This test determines the presence or absence of HCV RNA. When HCV RNA is detected, the corresponding HCV RNA viral load will be reported.
This test is primarily used to monitor the HCV RNA viral load in patients undergoing antiviral therapy. This test can also be used to confirm the diagnosis of HCV infection in seropositive patients and determine if the patient has active viremia. This test is not intended for use as a screening test for the presence of HCV in blood or blood products.
Hepatitis C virus (HCV) can cause acute hepatitis. However, HCV infection presents most frequently as a chronic hepatitis diagnosed on the basis of liver enzyme profiles. Seventy-five to eighty percent (75-80%) of patients with acute HCV develop chronic hepatitis. Chronic hepatitis C is one of the major causes of cirrhosis, and the most common indication for liver transplantation in adults in the U.S. Chronic HCV infections may also be a major cause of hepatocellular carcinoma in the world.
