Potential Clinical and Economic Outcomes of CYP2C9 and VKORC1 Genotype-Guided Dosing in Patients Starting Warfarin Therapy You JHS et al. - Genotype-guided dosing for warfarin therapy does not appear to be cost-effective, with the potential ICER per QALY being >$50,000. Lowering the genotyping cost, improving effectiveness of INR control of the genotype-guided dosing algorithm, and applying the algorithm in practice sites with high out-of-range INRs would improve the cost-effectiveness of the dosing algorithm.
