EST Becomes ANAB/ANSI Certified

To Our Friends and Colleagues,

Since 1993, EST has provided industry-leading environmental microbiological analyses for the water treatment and healthcare sectors. EST recognized early on the need for an ISO accreditation to provide our customers the confidence in our policies, procedures, and results. At that time, the company focused on both industrial hygiene and environmental laboratory work, making an accreditation from the American Industrial Hygiene Association (AIHA) the best fit. As EST has continued to grow, there has been a need for additional accreditations such as our CDC Elite proficiency for Legionella. The value of the ISO Certification has been increasingly emphasized as our environmental microbiological analysis services have increased. In response to this, in 2022 EST made the decision to move from an AIHA driven ISO Accreditation to an ANSI National Accreditation Board (ANAB) based ISO Accreditation.

EST Becomes ANAB/ANSI Certified

This change does not affect the services we offer, nor does it impact on the quality of our analysis. We believe that an ANAB ISO accreditation is better suited to the current needs of our clients. ANAB is a testing board used in over seventy-five countries, and by every major US Federal Agency, providing EST with opportunities of greater proficiency of service to our global client base. ANAB outlines the comprehensive process used to evaluate and certify laboratories here, guaranteeing superior and reliable services.

If you have any questions, please feel free to contact us using any of the links below or on our Contact Us page. You may also download our new Accreditation Documents located in the Documents section of our website. As EST continues to grow and expand, we would like to take this opportunity to thank all our clients. If not for you, we would not be here. EST is passionate about providing you with the best environmental microbiological solutions to provide safe facilities to protect you and your clients and will continue to do so for years to come.


Thank you,

Dr. Richard Miller

Chief Scientific Officer and President
