| Testing Schedule | Thursday |
| Expected TAT | may not be reported until next day |
| Clinical Use | HCV viral genotype is used to predict the likelihood of therapeutic response and determine duration of treatment. Patient must have a viral load of > 500 IU/mL for Genotype to be determined. |
| Notes | If the HCV genotype cannot be determined by PCR, the specimen will be sent out for HCV genotype sequencing analysis. Reflex Order Code [6906215] .HCV High-Resolution Genotype | Result Code [6906217] HCV Hi-Res Geno An additional CPT code 87902 will apply. |
