Phigenics Launches Its Next Day Legionella PCR Validation Test

Building on its patented Phigenics Validation Test® (PVT) TimeZero™ method, which is the fastest and most accurate Legionella and total heterotrophic aerobic bacteria (THAB) testing service, the Phigenics Research and Innovation Lab is excited to announce its most recent innovation, the Next Day Legionella PCR.

This new testing service offered by Phigenics detects Legionella DNA by the Polymerase Chain Reaction (PCR), which is the exponential amplification of a target sequence of DNA. Facility managers and building owners rely on the detection of Legionella sp. DNA for fast, preliminary results to indicate whether or not building water systems are well-managed. The use of PCR in water validation testing  was instrumental in allowing New York City health officials to rapidly identify the source of a Legionnaires' disease outbreak in 2015.

The provision of the defensible, guaranteed Next Day Legionella PCR result is due to Phigenics' Ultra-Rapid DNA Extraction (P.U.R.E.)™ protocol. "The new, innovative and advanced P.U.R.E.™ protocol provides superior results sooner," says Dr. WillIam McCoy, Phigenics Co-Founder and Chief Technology Officer. "When compared to traditional Legionella ISO 11731 culture results, the negative predictive value of this test is ≥ 99%." A limitation of the detection method, as with currently marketed PCR products, is that it cannot differentiate between viable and non-viable Legionella. Therefore, the new protocol is primarily useful as a negative screen to predict culture-negative results in building water systems.

The Next Day Legionella PCR is an enhancement to the industry-leading PVT PREMIUM product line, which delivers the fastest, most accurate and most comprehensive Legionella testing service. The PVT PREMIUM Potable and PVT PREMIUM Utility testing services apply both the TimeZero™ test method and P.U.R.E.™ protocol. Results from these tests are useful for the validation of biological hazard control in water systems such as those in healthcare facilities, hotels, commercial buildings, cooling towers, pools, spas, and from any other water systems in the built environment.
