The right medication shouldn’t be a guessing game.
PGX testing looks at a patient's DNA to see how their body handles specific drugs. Instead of adjusting medications after problems show up, providers get that information upfront.
MD Diagnostics runs PGX testing in-house at our CLIA-certified lab in St. Louis. Same speed and support you're used to from us — just applied to genetics.
Hospitalizations per year from adverse drug reactions
Genetic data up front means less trial-and-error prescribing and fewer callbacks to adjust dosages.
Higher ADR risk for patients on 7+ medications
Catch drug-gene conflicts before they become ER visits. Especially critical for patients on multiple meds.
FDA-approved medications covered
Know whether a patient metabolizes a drug too fast, too slow, or normally — before writing the script.
When residents are on seven, eight, ten medications, the risk of a bad reaction goes up fast. PGX testing helps care teams figure out which drugs are actually working with a resident's biology — and which ones might be causing more harm than good. Fewer adverse events, fewer falls, fewer readmissions.
When a patient isn't responding to a medication the way you'd expect, PGX results can tell you why. It's one more data point to support your clinical judgment — especially useful when starting treatments that have a lot of genetic variability.
Pain meds have narrow windows and wide variation between patients. PGX testing shows how someone metabolizes pain relievers and anti-inflammatories, so you can build a plan that actually works without overshooting or underdosing.
The PGX panel covers medications across these therapeutic areas:

Our Molecular UTI test uses qPCR technology to identify infectious organisms quickly and accurately, often within 24 hours.
Unlike traditional culture methods, molecular testing can detect up to 99% of infectious agents, including antibiotic-resistant strains that may be missed. Each report includes antimicrobial therapy guidance to help providers make informed treatment decisions.
Chronic and non-healing wounds often involve multiple organisms. Traditional culture methods may not capture the full picture.
Our molecular wound panel identifies 46 infectious organisms and 42 antibiotic resistance genes. PCR technology provides a more complete view of complex infections, helping providers target the primary pathogens responsible for delayed healing.
This PCR-based respiratory panel detects COVID-19, Influenza A & B, and RSV from a single nasal swab.
Because these illnesses share symptoms and co-infections are possible, accurate detection is critical. Our multiplex testing provides highly sensitive results to support faster and more precise treatment decisions.
Onychomycosis (nail fungus) affects many patients and can be difficult to diagnose visually.
Traditional testing methods can be slow or inaccurate. Our qPCR-based fungal test delivers rapid, highly precise detection, including resistant strains that standard methods may miss. This allows providers to confirm diagnoses quickly and guide effective antifungal therapy.
Pharmacogenetic Testing
Understand how your genes impact the way your body responds to medications. This test gives providers the insight to tailor treatments to each patient, reducing the risk of side effects and improving overall effectiveness. It is especially valuable for patients prescribed blood thinners, insulin, diabetes medications, or pain relievers drugs most often linked to complications and hospital admissions.
Molecular UTI
MD Diagnostics' Molecular UTI testing employs cutting-edge molecular techniques to deliver exceptionally precise and fast 24-hour identification of infectious organisms. MD Diagnostics creates individualized antimicrobial therapy recommendations for every urinary tract infection case. This qPCR-based UTI analysis empowers medical providers to make critical and prompt treatment decisions that enhance patient outcomes through the detection of 99% of all infectious agents and antibiotic-resistant microorganisms frequently overlooked by traditional culture methods.
Optimized Molecular Wound
Effectively address skin and soft tissue infections, eliminate diagnostic delays, and prevent infection advancement through MD Diagnostics' extensive molecular wound analysis panel. MD Diagnostics' testing platform delivers comprehensive data on 46 infectious organisms and 42 genes associated with antibiotic resistance.
Traditional culture techniques fail to provide a complete picture of microbial communities or all microorganisms present within wound sites. PCR technology, however, offers quantitative assessment of every microorganism involved in these complex multi-pathogen infections. This comprehensive analysis enables healthcare providers to target the primary organisms causing chronic, non-healing wounds.
Molecular Respiratory Testing
This advanced PCR test identifies COVID-19, Influenza A & B, and RSV from a single nasal swab. Because these illnesses share similar symptoms and co-infections are possible accurate detection is essential. Our multiplex technology delivers highly sensitive results, helping providers confirm diagnoses quickly and choose the most effective treatment.
Molecular Fungal Testing
Onychomycosis (nail fungus) affects up to 14% of people and can be difficult to diagnose by appearance alone. Traditional methods like culture or KOH prep are slow and often inaccurate. Our qPCR-based Molecular Fungal test delivers rapid, highly precise detection identifying 99% of fungal organisms, including resistant strains that standard tests may miss. This allows providers to confirm diagnoses quickly and guide effective antifungal treatment.
