What PGX Does

Stop Guessing. StartPrescribing With Data.

Pharmacogenetic testing — PGX — analyzes a patient's DNA topredict how they'll metabolize specific medications. Instead of trial-and-errorprescribing, you get a clear picture of which drugs are likely to work, whichto avoid, and which need dose adjustments.

For patients on multiple medications, withtreatment-resistant conditions, or in long-term care settings where adversedrug reactions carry real risk, PGX moves prescribing from educated guess toinformed decision.

The Five Panels

Five Panels Built AroundReal Prescribing Decisions

Each panel is designed for a specific clinical context andtests the medications you're actually prescribing — not a generic dump of everygene-drug interaction in the literature.

Neuropsych Panel

For psychiatrists, mental health facilities, recoverycenters, and behavioral health programs. Tests metabolism of theantidepressants, antipsychotics, mood stabilizers, and anxiolytics mostcommonly prescribed in mental health and addiction recovery settings.

Best fit for: Outpatient psychiatry, inpatientbehavioral health, residential recovery, dual-diagnosis programs.

More Info

Pain Management Panel

Built for pain specialists managing patients on opioid andadjunctive therapy. Tests metabolism of common narcotics, NSAIDs, musclerelaxants, and neuropathic pain agents — so you can identify ultra-rapidmetabolizers, poor metabolizers, and patients at elevated risk before titrationbecomes a problem.

Best fit for: Interventional pain practices, chronicpain clinics, palliative care, post-surgical pain management.

Cardiopulmonary Panel

Covers the cardiovascular and pulmonary medications wheregenetic variation most directly affects outcomes — including anticoagulants,antiplatelets, statins, beta-blockers, and select bronchodilators.

Best fit for: Cardiology, pulmonology,anticoagulation clinics, primary care managing complex cardiac patients.

For Long-Term Care & Skilled Nursing

Built for the Realities of Long-Term Care

Long-term care residents are the highest-risk PGX populationin medicine — polypharmacy is the norm, adverse drug events drive avoidablehospitalizations, and behavioral health populations in skilled nursing andLevel-One psych facilities are often on regimens that have never beengenotype-matched.

We work directly with:

Skilled nursing facilities
Residential care facilities (RCF)
Level-One psych facilities
Recovery and behavioral health residentialprograms
Long-term acute care hospitals

Why MD Diagnostics

Why MDD for PGX

Performed entirely in-house. No referencelabs. No handoffs. As one of the few independent labs in the Midwest running pharmacogenetic testing on-site, we control the timeline and the quality from specimen to report.
Independent and family-owned. We answer to our clients, not to a health system or private equity ownership.
Built on a clinical foundation. Our lab has been running molecular and toxicology testing since 2008. PGX is an extension of work we've been doing well for years — not a side experiment.
Real support, not a portal. When you have a question about a result, you get a human who knows the answer.
