Preventing Healthcare-Associated Infections (HAIs) since 1993!

In 1993, a local hospital contacted EST concerned over the potential for Healthcare-Associated Infections (HAIs) involving Aspergillus related to construction projects.  Uniquely positioned with expertise in environmental microbiology, epidemiology, and industrial hygiene, EST was able to answer that call and assist that facility.  From that initial contact Dr. Miller’s expertise in Legionella detection and isolation provided our healthcare customers with another powerful tool to prevent Legionnaires’ Disease.  Over the years new environmental concerns have come to light, and EST continues to innovate to meet these demands.  Our team has expanded expertise since that time and can develop a specific testing program designed to fit the needs of your facility or healthcare network.  Whether it is emerging pathogens, multidrug-resistant (MDR) bacteria, or microbiological contamination of pharmaceutical spaces, EST can provide the expertise and solutions you need.

Powerful tools to aid the Healthcare Industry prevent HAIs

Since 1993, EST has been a leader in environmental sampling for the healthcare industry.  Providing air quality testing for construction projects along with Legionella testing for cooling towers and potable water EST gives our healthcare partners the tools they need to minimize infections. 

Legionella Testing

    • Standard turnaround 7-10 days

    • ISO 11731:2017 process method

    • Reporting pneumophila Serogroup 1 (SG 1), L. pneumophila SG 2-14, and L. non-pneumophila species

    • Rapid turnaround in 96 hours

    • Traditional culture processing

    • Reporting pneumophila SG 1, L. pneumophila SG 2-14, and L. non-pneumophila species

    • Same Day or Next Business Day turnaround
    • Viable specific version of Legionella qPCR ISO/TS 12869:2019
    • Validated to accurately report CFU/ml
    • Reporting viable pneumophila SG 1 and L. pneumophila SG 2-15
  • CMS/Environmental Waterborne Pathogens Test

      • ANSI/ASHRAE Standard 188-2021 drove the need to perform Legionellatesting as validation of an implemented and verified WMP.  However, there are additional waterborne pathogens that may be present that also need to be kept under surveillance.  In the above-mentioned memorandum CMS listed six additional pathogens to keep watch for in patient populations, especially the immunocompromised.  In response, EST developed a new combination Waterborne Pathogen Test. Because these other CMS pathogens have been overshadowed by the regulatory and legal focus on Legionella, these waterborne pathogens are sometimes referred to as the “Forgotten Six”:
        • Pseudomonas aeruginosa
        • Acinetobacter species
        • Burkholderia cepacia complex
        • Stenotrophomonas maltophilia
        • Mycobacterium species – Non-tuberculous (NTM)
          • Total NTM
          • M. avium
          • M. intracellulare
        • Fungi (Molds and Yeast)
      • All pathogens also available as individual analysis.
  • Let EST help validate your facility’s cleaning and disinfection procedures for control of Candida auris2and other menacing pathogens1.  By using our Candida auris & Antibiotic-Resistant Pathogens Test, you can definitively screen for a wide range of drug-resistant pathogens that can survive on surfaces and lead to costly HAI.
      • Candida auris
      • Staphylococci – MRSA/MSSA/MRSE/ VRSA
      • Enterococci – VRE
      • C. diff (Clostridioides difficile)
      • Carbapenem Resistant Enterobacterales (CRE) – Klebsiella pneumoniae / coli / others
      • Acinetobacter baumannii
      • Pseudomonas aeruginosa
    • All pathogens also available as individual analysis.
  • Analyses that measure regulatory (City or State) controlled disinfection parameters:
    • Escherichia coli (E. coli)
    • Total Bacterial Count
  • Analyses that measure Legionella control:
    • L. pneumophila serogroup 1
    • L.  pneumophila serogroup 2-14
    • Legionella (other species)
  • Analyses that measure other associated waterborne pathogen control:
      • Pseudomonas aeruginosa
      • Mycobacterium species – Non-tuberculous (NTM)
          • Total NTM
          • M. avium
          • M. intracellulare

Dr. Legionella™ And EST

With all our great Legionella services you get access to Dr. Legionella and his extensive Legionella knowledge and experience.

COVID-19 and Legionella

The impact COVID-19 has had on everyone extends to building water systems, both cooling towers, and potable water systems. Inactivity and limited use can contribute to the formation of biofilm allowing for Legionella proliferation. EST can assist in developing a reopening plan for your facility, including highly effective re-commissioning disinfection procedures and follow-up validation testing.
