NEW ORDER CODE
Hepatitis C Virus Genotyping
Order Code: MHCVG
Reference Laboratory: Mayo HCVG
New test codes MHCVG Hepatitis C Virus Genotyping (Mayo test ID HCVG) (CPT 87902) and HCVGR Hepatitis C Virus Genotyping Resolution (Mayo test ID HCVGR) (CPT 87902) will be available effective August 30, 2022.
Hepatitis C Virus Genotyping Resolution will be performed at an additional charge if indicated:
|
Hepatitis C virus (HCV) genotyping result |
Interpretation |
Resolution test (reflex test) performed? |
|
1a |
1a is the definitive subtype/genotype |
No |
|
1b |
1b is the definitive subtype/genotype |
No |
|
2 |
2 is the definitive genotype |
No |
|
3 |
3 is the definitive genotype |
No |
|
4 |
4 is the definitive genotype |
No |
|
5 |
5 is the definitive genotype |
No |
|
1 |
A definitive genotype/subtype (1a, 1b, 6) could not be assigned. Resolution testing ordered. |
Yes |
|
1a, 2 (any 2 genotypes) |
Result may be due to mixed genotype infection, recombination of HCV genotypes, or assay probe cross-reactivity. |
No |
|
1, 3 (2 genotypes with a 1 no subtype) |
Result may be due to mixed genotype infection, recombination of HCV genotypes, or assay probe cross-reactivity. Resolution testing ordered. |
Yes |
|
HCV not detected |
Assay failed to detect HCV RNA. |
No |
|
Indeterminate (undetermined genotype) |
HCV RNA detected, but genotype could not be determined. Resolution testing ordered. |
Yes |
|
Indeterminate (mix) |
Result may be due to mixed genotype infection, recombination of HCV genotypes, or assay probe cross-reactivity. |
No |
An "Undetected" result indicates the absence of detectable hepatitis C virus (HCV) RNA in the specimen.
