About AGT Labs IH Testing
Houston's Accredited Industrial Hygiene Testing Laboratory
Our Mission
AGT Labs is dedicated to protecting worker health through accredited, defensible industrial hygiene testing. Our mission is to provide EHS managers, industrial hygienists, and safety directors with the accurate, timely analytical data they need to ensure workplace compliance and safeguard employees from occupational hazards.
Who We Are
AGT Labs operates one of Houston's most comprehensively accredited industrial hygiene testing laboratories. Based in Houston's East End industrial corridor at 10200 East Freeway, Suite 101, our facility is purpose-built for IH analysis — every instrument, method, and quality protocol is designed specifically for occupational exposure assessment.
Unlike general environmental labs that offer a few IH methods as an afterthought, industrial hygiene testing is our core competency and sole focus. Our laboratory team performs every analysis in-house using validated NIOSH, OSHA, and EPA methods under ISO/IEC 17025 quality management. No subcontracting. No outsourcing. This means faster turnaround, tighter chain-of-custody control, and a single point of accountability from sample receipt to final report.
Industrial Hygiene is Our Sole Focus
We aren't a generalized lab. Every piece of instrumentation and every quality control protocol we've built is dedicated entirely to occupational exposure analysis, ensuring your samples receive the specialized attention they require.
