Hepatitis C Virus (HCV) Genotype with Reflex to HCV NS5A Drug Resistance by Sequencing
Copy Utility
Ordering Recommendation
Order before initiating treatment with NS5A inhibitors. Use to determine HCV type 1-6 after molecular confirmation of positive HCV screen. If genotype “1a or 1b” is determined, testing will reflex to HCV NS5A for genotype differentiation and drug resistance by sequencing.

Interpretive Data
Refer to report.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
Laboratory Developed Test (LDT)
Note
This test may be unsuccessful if the HCV RNA viral load is less than log 3.6 or 4000 IU/mL. If initial result is Type "1a or 1b", then HCV NS5A Drug Resistance by Sequencing will be added. Additional charges apply.
