Warfarin Sensitivity Genotype by Sequence Analysis, Blood
Method Description Describes how the test is performed and provides a method-specific reference
Genomic DNA is extracted from whole blood. The CYP2C9 gene and VKORC1 promoter are amplified by PCR. The PCR product is then purified and sequenced in both directions using fluorescent dye-terminator chemistry. Sequencing products are separated on an automated sequencer and trace files analyzed for variations in exons 3, 5, and 7 of the CYP2C9 gene and the VKORC1 gene promoter using mutation detection software and visual inspection.(Unpublished Mayo method)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.
