Hepatitis C Virus Genotype, Serum
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
The following algorithms are available in Special Instructions:
-Testing Algorithm for the Screening and Diagnosis of Hepatitis C
-Chronic Hepatitis C Treatment and Monitoring Algorithm: Interferon-Free Combination Therapy
Specimen Type Describes the specimen type needed for testing
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Collection Container/Tube: Serum gel
Submission Container/Tube: Plastic vial
Specimen Volume: 5 mL
1. Spin down and separate serum from cells within 6 hours of collection.
2. Freeze serum immediately and ship specimen frozen on dry ice only.
3. If shipment will be delayed for >3days, freeze serum at -20 degrees C or colder (up to 42 days) until shipment on dry ice.
Additional Information: Specimens should contain a recommended minimum HCV viral load of 500 IU/mL.
If not ordering electronically, complete, print, and send a General Request Form (T239) with the specimen (http://www.mayomedicallaboratories.com/it-mmfiles/general-request-form.pdf).
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
