Pharmacogenomics: Knowing the possibilities for effective treatment

Quest Diagnostics offers one of the most comprehensive pharmacogenomics test panels available to help you gain insight into a patient’s potential response to medications and optimize their treatment considerations and outcomes. This includes information for over 280 drugs across 44 genes*. This full panel is particularly advantageous for patients on multiple medications who may otherwise require multiple panels—all at a low cost and coming from a company you trust to meet all of your lab needs.

The Pharmacogenomics Panel from Quest provides pharmacogenetic information for 44 genes, and reports information across multiple classes of medications:

  • Anesthesia
  • Cancer/Hematology
  • Cardiovascular
  • Diabetes
  • Gastrointestinal
  • Gaucher Disease
  • Infectious Disease
  • Neurology
  • Pain
  • Psychiatry and Addiction
  • Rheumatology
  • Urologicals

Physicians receive test results in a comprehensive and easy to understand report that may include dosing guidelines from CPIC®, FDA-approved labeling, and other pharmacogenomic consortia. Results can be utilized as a reference for your patients throughout their lifetime.

Why Pharmacogenomics?

The Quest Diagnostics Pharmacogenomics Panel is based on pertinent literature sources that may provide clinical insights to help inform treating physicians about a patient’s genetic attributes to help optimize patient treatment considerations and outcomes.**

Pharmacogenetics/pharmacogenomics is the study of how inherited genetic differences impact the way drugs or medications affect a person. These genetic differences can impact the way a drug is absorbed or metabolized and thereby influence drug response. Pharmacogenomic tests may provide information about a person’s genetic makeup to help doctors decide which medications and doses might work best for him or her. Pharmacogenomic testing can also help reduce the time and costs associated with a trial-and-error approach to treatment.1

Avoiding adverse drug reactions can make a difference

The power of Pharmacogenomics

The Quest Diagnostics comprehensive pharmacogenomics test panel (PGx) offers insights into patient potential responses to different medications and over 280 drugs.*

The panel may determine:

  • Risk of adverse drug reaction
  • Efficacy (i.e., will it work?)

A Pharmacogenomics Panel may provide additional insights to:

  • Help to identify patients who may react negatively to certain medications
  • Help to achieve better outcomes on a patient-by-patient basis

*Pharmacogenomic information is not assessed for potential alternative medications. These data are provided as alternatives to consider based on information reported in the literature due to pharmacogenomic contraindications in other medications.
