Dear Practitioner,

Your patient has expressed an interest in pharmacogenetic testing. As you may be aware, Pharmacogenetic testing is rapidly becoming a part of optimum medical practice and, for some medications, it has become the standard of care. This important laboratory information gives healthcare professionals the ability to predict in advance how a patient will respond to certain prescribed medications. The intention is to reduce the risk of adverse drug reactions and to assist you in optimizing the selection of medications and dosing for maximum therapeutic effect.

Because pharmacogenetics is such a new field, PGXL Laboratories has made specific information available so that you may determine if pharmacogenetics testing would help you to better manage your patient. That information is available without charge or obligation at our website: www.pgxlab.com.

PGXL Laboratories is dedicated to helping physicians and other healthcare professionals learn how to use pharmacogenetic testing to better serve their patients.

If you have questions about pharmacogenetic testing or about PGXL Laboratories, we are happy to speak with you and there is no charge for any of our consultations. Please call PGXL Laboratories at (502) 569-1584 or visit our website. We are a full-service CLIA-certified clinical laboratory and we bring the benefits of pharmacogenetic testing to you and your patients with the highest of quality standards.
