Interleukin 28B (IL28B) Polymorphism (rs12979860), Saliva

Method Description Describes how the test is performed and provides a method-specific reference

Real-time PCR with allele-specific probes is used to detect a single-nucleotide polymorphism (SNP) (rs12979860 CT) on chromosome 19q13. The rs12979860 SNP maps 3 kilobases upstream of the IL28B gene (OMIM: 607402) which encodes the type III interferon IFN-Lambda 3. No other polymorphisms are detected by this assay. Molecular-based testing is highly accurate, but as in any laboratory test, rare diagnostic errors may occur. Specimens producing unusual results, or results not consistent with patient outcome, may be evaluated by bidirectional DNA sequencing.(Unpublished Mayo method)

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Tuesday; 9 a.m.

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

1 day (not reported on Saturday or Sunday)

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result

7 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

Saliva: 2 weeks; Extracted DNA: 2 months

Performing Laboratory Location The location of the laboratory that performs the test
