This result signifies that the patient has two copies of a no function allele. Based on the genotype result, this patient is predicted to have low SLCO1B1 function. This patient may be at a high risk for an adverse response to medications that are affected by SLCO1B1 (i.e. statins). To avoid an untoward drug response, dose adjustments or alternative therapeutic agents may be necessary for medications affected by SLCO1B1. Please consult a clinical pharmacist for more specific information about how SLCO1B1 function influences drug dosing.
