Pharmacogenomics Physician Information

What is the pharmacogenomics (PGx) clinic?

Pharmacogenomics uses an individual’s genetic information to help guide the selection of a medication or dose of a medication to optimize treatment response and minimize adverse drug events.  The pharmacogenomics clinic at Pharmacy Plus helps individuals understand how their DNA influences current and future treatments prescribed.

Our specially trained pharmacists will:

  • Meet with your patient to determine if pharmacogenomic testing is indicated by evaluating your patient’s medical history and medications
  • Contact the patient’s physician with a recommendation for a pharmacogenomic test, where appropriate
  • Interpret the results and provide a consult note with treatment recommendations
  • Counsel the patient on their pharmacogenomic test results

When is PGx testing indicated or recommended?

Pharmacogenomic testing is recommended:

  • Prior to prescribing certain medications to predict if the patient will respond to treatment, experience an adverse drug event, or guide the initial dose
  • After an adverse drug event if genetic testing was not ordered previously for a known drug-gene pair

How do I order a PGx test?

Ordering a pharmacogenomic test is easy. Contact our pharmacogenomics team and we can help you identify a pharmacogenomic test to order that is most appropriate for your patient.

Sample required for PGx testing

Genetic testing can be performed by collecting a sample of a patient’s blood, saliva, or by swabbing their cheek. The lab processes the sample. Genetic test results are usually available within 5-10 business days, but it can vary from lab to lab.

How much does PGx testing cost?

Coverage for pharmacogenomic testing depends on the patient’s insurance. We recommend that your patient contact their insurance company to inquire about coverage for pharmacogenomic testing and any copays.

Pharmacogenomics Clinic Fee

There will be a $25 clinic fee charged to the patient during the pharmacogenomics counseling session after pharmacogenomic test results have returned.
