What is it indicated for?

The eSensor® Warfarin Sensitivity Saliva Test is an in vitro diagnostic for the detection and genotyping of the *2 and *3 alleles of the cytochrome P450 (CYP450) 2C9 gene locus and the Vitamin K epoxide reductase C1 (VKORC1) gene promoter polymorphism (-1639G>A) from genomic DNA extracted from human saliva samples collected using the the Oragene® Dx Device, as an aid in the identification of patients at risk for increased warfarin sensitivity.

Indications for use as stated in the FDA summary.
