Pharmacogenomic testing definitively determines which medication will work best for the patient

Discuss the testing honestly. Pharmacogenomic testing informs about drug metabolism through CYP450 enzyme variants, but evidence for predicting overall treatment response is evolving. Discuss what the test can and cannot tell, costs, and that results inform but do not replace clinical judgment

Refuse the testing as it is not adequately supported by evidence

Order the test without discussing limitations since the results are straightforward
