A short description of the method used to perform the test
Polymerase Chain Reaction (PCR); Sequencing
NY State Available
Indicates the status of NY State approval and if the test is orderable for NY State clients.
Lists a shorter or abbreviated version of the Published Name for a test
HCV RNA Genotype 3 NS5a Drug Resist
Lists additional common names for a test, as an aid in searching
HCV NS5a Subtype
Describes the specimen type validated for testing
Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Submit one of the following:
Draw blood in a (lavender-top) EDTA tube(s). (Plasma gel tube is acceptable.) Spin down and send 2 mL plasma refrigerated in a plastic vial.
Draw blood in a plain red-top tube(s). (Serum gel tube is acceptable.) Spin down and send 2 mL serum refrigerated in a plastic vial.
Specimen Minimum Volume
Defines the amount of sample necessary to provide a clinically relevant result as determined by the Testing Laboratory
Reject Due To
Identifies specimen types and conditions that may cause the specimen to be rejected
| Hemolysis || Mild OK, Gross reject |
| Lipemia || Mild OK, Gross reject |
| Icterus || NA |
| Other || Heparin plasma |
Specimen Stability Information
Provides a description of the temperatures required to transport a specimen to the performing laboratory, alternate acceptable temperatures are also included
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
The clinical significance for antiviral therapy of NS5a resistance associated variants may vary according to the clinical status and antiviral treatment experience of the HCV-infected patient.
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
HCV NS5a Subtype: Not Predicted
Describes how the test is performed and provides a method-specific reference
This assay is designed to amplify HCV Genotype 3 and may not successfully amplify other HCV genotypes.
This test utilizes RT-PCR and DNA sequencing to detect the presence of treatment-emergent HCV genotype 3 NS5a variants associated with NS5a inhibitor antiviral therapy.
Indicates whether the report includes an additional document with charts, images or other enriched information
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.
4 to 18 days
Performing Laboratory Location
Indicates the location of the laboratory that performs the test

Provides information regarding the medical device classification for laboratory test kits and reagents. Tests may be classified as cleared or approved by the US Food and Drug Administration (FDA) and used per manufacturer instructions, or as products that do not undergo full FDA review and approval, and are then labeled as an Analyte Specific Reagent (ASR) product.
This test was developed and its analytic performance characteristics have been determined by Focus Diagnostics. It has not been cleared or approved by the FDA. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposed.
CPT Code Information
Provides guidance in determining the appropriate Current Procedural Terminology (CPT) code(s) information for each test or profile. The listed CPT codes reflect Mayo Clinic Laboratories interpretation of CPT coding requirements. It is the responsibility of each laboratory to determine correct CPT codes to use for billing.
CPT codes are provided by the performing laboratory.
