3/12/2010 -- Phigenics, LLC has again achieved the Centers for Disease Control and Prevention, (CDC) Environmental Legionella Isolation Techniques Evaluation (ELITE) certification for the detection, recovery and enumeration of Legionella in water samples. Phigenics has successfully passed the two rounds of proficiency testing necessary to obtain this recertification, which is valid until March of 2011. Phigenics was one of the first commercial labs to achieve this certification in 2009.
The Phigenics Validation Test (PVT) is a field method for the quantitative determination of viable Legionella and total heterotrophic aerobic bacteria. This method has been proven reliable for determining viable cell concentrations of Legionella pneumophila, Legionella species and total heterotrophic aerobic bacteria. In comparison to standard methods, the new protocol has been shown to be more accurate, faster and more convenient.
Measuring viable Legionella and other bacteria using standard culture methods requires shipment of water samples to an analytical laboratory. The results typically take 12-14 days which can leave facilities in a holding pattern. The shipment of water samples can cause unpredictable changes. In some water samples, viable bacteria increase during transit and in other samples they decrease. When the facility receives their Legionella results, these challenges can make interpretation and decision-making difficult.
The patents pending Phigenics Validation Test (PVT) completely eliminates the need to ship water samples, thereby giving more reliable data about the water system. The PVT is a field sampling protocol to obtain viable cell counts (CFU/ml) for total heterotrophic aerobic bacteria, Legionella pneumophila (serogroup 1 and serogroups 2-14) and all non-pneumophila Legionella species. Data is obtained for the exact moment when the PVT Field sampler contacts the water sample, which means shipment of water samples to a laboratory is not required. Additionally, the time required to obtain results is reduced 75-80% compared to the Standard Method for Legionella.
The ability to post, track and manage results on a custom designed, confidential website is also available.
