5 - 7 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

This assay is used for genotyping IL-28B rs12979860.
IL28B genotype should be interpreted in the context of other clinical factors. This assay detects only a single base change in the IL28B gene (single nucleotide polymorphism rs12979860 C/T). No other polymorphisms are detected by this assay. Rare sequence polymorphisms close to rs12979860 may interfere with the genotype results of this assay.
This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration.
Real-time polymerase chain reaction (PCR) with allele-specific TaqMan® probes is used to detect a single nucleotide polymorphism (SNP) (rs12979860 C/T) on chromosome 19q13. The rs12979860 SNP maps 3 kilobases upstream of the IL28B gene (OMIM 607402), which encodes the type III interferon-λ3.
