Specimen Requirements

Specimen

Serum or plasma

Volume

2.5 mL

Minimum Volume

700 μL (Note: This volume does not allow for repeat testing.)

Container

Causes for Rejection

Incorrect anticoagulant; PPT™ not centrifuged

Test Details

Use

Determine the number of international units (IU) of hepatitis C virus (HCV) RNA per milliliter in serum or plasma in known HCV-positive patients

Limitations

The quantifiable range of the assay is 15 IU/mL to 100,000,000 IU/mL.
