Analysis of one of the largest PFAS blood datasets found multiple PFAS, the man-made ‘forever chemicals’, in 98.5% of over 10,500 people tested in US study.​

“…the study offers a greater understanding of what widespread, combined PFAS exposure may mean for human health…” - Laura Labay, NMS Labs Principal Toxicologist and lead author of the newly published research in Journal of Occupational and Environmental Hygiene.

Mast cell disorders remain a persistent diagnostic challenge. Symptoms are often non-specific, and key biomarkers such as histamine are transient, making accurate detection difficult within a narrow window.​

🧪NMS Labs now offers urinary N-Methylhistamine testing to support the evaluation and longitudinal monitoring of mast cell activation. As a stable metabolite of histamine, N-Methylhistamine extends the detection window and enables detection of mast cell activity even after symptoms have resolved.​

✅This test supports clinical assessment of conditions such as Mast Cell Activation Syndrome and severe allergic reactions, including anaphylaxis, while helping reduce repeat collections and inconclusive results.​

On National Fentanyl Awareness Day, we remember those lost to illicit fentanyl poisoning and acknowledge the ongoing efforts to address this evolving crisis.​

The illicit drug supply has changed. Substances are rarely what they seem, often containing a mix of fentanyl, other synthetic opioids, stimulants, and additional unknown compounds. This unpredictability continues to increase risk and complicate response efforts.​

NMS Labs supports healthcare providers, public health agencies, and law enforcement through comprehensive toxicology testing and research, helping detect fentanyl and other emerging substances in an increasingly complex landscape.​

We remain committed to advancing awareness, detection, and response through science.​

⚠️Meaningful workplace safety isn’t just about measuring exposure; It’s about turning data into informed decisions that protect workers over the long term.​
🌎On World Day for Safety and Health at Work, we recognize the global effort to advance safer, healthier workplaces through awareness, prevention, and collaboration.​
At NMS Labs, this mission is reflected in how we support occupational health and industrial hygiene professionals every day.​
Through our exposure monitoring capabilities, we help organizations connect exposure insight to employee health, using validated testing in blood, urine, and other biological specimens to assess potential toxicity. From high-interest concerns like PFAS and heavy metals to VOCs, pesticides, and other emerging contaminants, our comprehensive test menu supports both routine and complex workplace exposure scenarios.​
👷We work closely with our clients to establish effective testing strategies including defining baseline exposure for developing protocols tailored to various industries, risks, and regulatory needs.​

A new episode of Corrections Unfiltered launched and features insights on one of the fastest-growing threats in correctional facilities: “wasp dope.”

In this episode, NMS Labs Drug Chemistry Technical Manager, Amanda Andrews, joins Alishia McColl of the Washington State Department of Corrections to discuss how drug contraband is evolving from synthetic cannabinoids like K2 to papers adulterated with pesticides.

This podcast covers:
• How Drug ID testing works—and why confirmatory testing matters
• The limitations of field test kits in correctional settings
• Emerging risks tied to drug-impregnated paper and pesticide exposure
• How expanded testing capabilities can help improve safety for staff and inmates

As drug threats continue to evolve, having the right testing strategy in place is critical.
