HelpTest Code HCVGT Hepatitis C Virus (HCV) Genotyping (Plasma)
Clinical Indications
Hepatitis C Genotyping can be used to help predict the
outcome
of therapy and to influence the choice of therapeutic drugs.
Clinical outcome depends on the genotype of the infection,
pretreatment viral load, and whether or not liver cirrhosis is
present. Genotypes 1a and 1b have the poorest clinical outcomes
with sustained viral response of only 46% with combination
antiviral therapy.

Epic Px Code: LAB2275
Specimen Collection Type
Preferred: PPT (pearl top EDTA)
Acceptable: Lavender (EDTA) or Yellow
(ACD
solution)
Minimum Collection Volume
2.0 mL
Reference Range
Genotypes: 1a, 1b, 2a/2c, 2b, 3, 4, 5, and 6
Critical Value
N/A
Interpretation
Detects all 6 HCV genotypes including
types 1-6 and subtypes 1a, 1b, 2a/2c, 2b. This test has a
limited
ability to detect mixed genotypes.
Rejection Criteria
Specimens beyond their acceptable length of time from
collection
as listed in the specimen handling, HCV
RNA
concentrations too low to allow for
genotype testing, concentrations too low to allow antiviral
resistance testing (patient must have a recent Hepatitis C
viral
load greater than 250 IU/mL).
