Hepatitis C Virus (HCV) Genotype with Reflex to HCV NS5A Drug Resistance by Sequencing
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.
New York DOH Approval Status
Lavender (EDTA), Pink (K2EDTA), Plasma Preparation Tube (PPT), or Serum Separator Tube (SST).
Separate from cells ASAP or within 2 hours of collection. Transfer 2 mL serum or plasma to an ARUP Standard Transport Tube. (Min: 1.5 mL)
Ambient: Unacceptable; Refrigerated: 72 hours; Frozen: 4 months
Polymerase Chain Reaction/Sequencing
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)
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.
