CMS Waterborne Pathogens Panel

 

Significance
There are a variety of microorganisms found in the water of healthcare facilities that are not generally pathogenic for healthy individuals but may be pathogenic for the immunocompromised patient. The conditions associated with increased risk of acquiring an infection from a waterborne pathogen include: hematological malignancy, immunosuppression, transplantation and burns. These infections can result in significant morbidity and mortality. The CMS pathogens panel is designed for use in healthcare facilities to evaluate the potential for exposure to six waterborne pathogens Legionella, Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Acinetobacter species, Burkholderia cepacia, and nontuberculous mycobacteria.

Test Method:
Legionella spp.
Special Pathogens Laboratory follows a modified version of the ISO Standard 11731:2017, Water Quality-Enumeration of Legionella. Special Pathogens Laboratory is accredited by the American Association for Laboratory Accreditation (A2LA), New York ELAP, and the State of Connecticut Department of Health to perform this test.

Modification of the ASTM International Standard Test Method for the Isolation and Enumeration of Pseudomonas aeruginosa from water (D5246) with the addition of direct plating in the event of high concentrations of the organism. Special Pathogens Laboratory is accredited by the American Association for Laboratory Accreditation (A2LA) to perform this test.
