Pseudalert method published as ISO worldwide standard

IDEXX Laboratories Inc, the rapid microbiological testing specialist for water, says its IDEXX Pseudalert method has been published as the International Organization for Standardization (ISO) worldwide standard, 16266-2, for the 24-hour detection of Pseudomonas aeruginosa in water.

Listed under ISO 16266-2:2018, Water Quality – Detection and Enumeration of Pseudomonas aeruginosa – Part 2: Most Probable Number Method, the Pseudalert method detects P. aeruginosa in 24 hours, ‘less than half the time of other commercially available methods’. IDEXX added: “It also has high sensitivity and specificity, requires no confirmation steps, and can be more easily used with water samples that have high levels of background flora.” 

Paul Balaam, senior Estates Officer at King’s College Hospital NHS Foundation Trust, which operates one of London’s largest and busiest teaching hospitals, added: “King’s College Hospital strives to maintain a bacteria-free environment, and part of ensuring a clean facility is regular testing for contaminants, including Pseudomonas aeruginosa. The IDEXX Pseudalert method’s acceptance as an ISO standard further validates that we are using the best solution on the market for our testing needs.” 

The Pseudalert method is also included in country-specific standards in the UK, Germany, France, and Italy, and has been shown to be ‘as accurate as, or more accurate than, the traditional method’ in two independent studies published in peer-reviewed journals.
