Based on the genotype result, this patient is predicted to be a CYP2C9 intermediate metabolizer (activity score of 1.5). This patient may be at risk for an adverse response to medications that are affected by CYP2C9. Please consult a clinical pharmacist for more specific information about how CYP2C9 intermediate metabolizer status influences drug dosing.
