+(4)S/PO/F

Ordering Instructions

If one or more of the following tests are to be ordered, only one EDTA plasma tube or one serum tube (minimum volume 2 mL) needs to be provided:

  • Hepatitis C Virus RNA Quantitation by RT-PCR
  • Hepatitis C Genotype with Amplification

In addition, positive HCV specimens will be stored by the laboratory for 1 month, so additional follow-up testing can be added to the original order by FAXing the completed “Additional/Add-on Laboratory Request” form to Spectrum Health Lab Central at 616-267-2751.
