Common Questions about Legionella Testing

icon-whatis
What is Legionella testing?

Legionella testing is the process of obtaining a water sample and analyzing it to detect the presence of the bacteria.

why-icon
Why are water systems tested for Legionella?

Legionella testing done to confirm effectiveness is defined as validation. Testing for Legionella is done to confirm that a Water Management Program is effective at controlling Legionella, which is defined as a hazard. It is also done to discover the source of exposure after a disease case is reported.

types-icon
What are the types of Legionella tests?

There are two general types of Legionella tests: Microbial culture tests (spread plates and field sampler “dipslides”) and molecular tests (Polymerase Chain Reaction, PCR). For microbial culture, L. pneumophila serogroup 1, serogroups 2-14 and Legionella spp. should always be determined for every isolate.

independent-icon
Why should my testing service be independent?

An independent, third-party testing service provides improved defensibility by removing real or perceived commercial conflict of interest or bias toward proprietary water treatment solutions.

where-icon
Where should I test for Legionella?

Sampling locations are decided by the Water Management Team. Locations may include incoming water, showers, misters, ice machines, faucets, cooling towers and decorative water features. Phigenics recommends collecting post-flush samples from plumbing fixtures, when Legionella testing is done as part of routine validation to confirm WMP effectiveness. Call us to learn why.

when-icon
When should I test for Legionella and how often?

Testing should be undertaken after a Water Management Team has confirmed that a program has been implemented as designed (verification). The frequency of testing is determined by the Water Management Team and is often monthly, quarterly or semi-annually.

how-icon
How should I respond to a positive Legionella test?

Any response should be predetermined and documented as a “contingency response” in the Water Management Program. Contingency responses should include a review of the verification data and may include activities such as flushing or hyperchlorinating the water system. Call us to learn more.

selection-icon
What is the CDC’s guidance for laboratory selection?

The CDC has five considerations for laboratory expertise: ELITE accreditation, the performance of culture method, level of identification, willingness to save samples and experience with environmental risk assessment and sampling. Click here to see how Phigenics meets the CDC’s criteria.

Industry-Leading Innovations.

The Phigenics Research and Innovation team is focused on innovations that improve speed, accuracy and comprehensiveness.

Innovations include the Phigenics patented TimeZero™ test method for quantitative measurement of viable Legionella and Total Heterotrophic Aerobic Bacteria (THAB).

Unlike the ISO 11731 spread plate method, the TimeZero test method begins culturing immediately in the field, thus entirely eliminating variations due to changes in water samples during shipment. Another innovation is the Phigenics Ultra Rapid DNA Extraction (P.U.R.E.)™ Protocol, which guarantees a Next Day Legionella PCR™ result by providing molecular-marker negative screen data. When the test result is negative, there is a 99.6% probability that culture-based results will also be negative.

Why Phigenics?

The CDC’s Considerations for Laboratory Expertise

Is the laboratory accredited for environmental testing and does it participate in a proficiency testing program for Legionella?

Phigenics Analytical Services Laboratory (PASL) is certified as proficient in the Environmental Legionella Isolation Techniques Evaluation (ELITE) program administered by the CDC.

Does the laboratory perform culture for Legionella?

Phigenics performs the laboratory culture method for both its Phigenics patented PVT TimeZero™ field test and ISO 11731 spread plate method.

What level of identification (species/serogroup) can the laboratory perform?

Phigenics performs comprehensive testing, including Legionella pneumophila (serogroups 1 and 2-14), non-pneumophila and Legionella species.

Is the laboratory willing to save isolates from samples and share them with public health laboratories if requested during an outbreak investigation?

Phigenics saves all isolates of Legionella from all samples and has extensive experience in helping our clients work with public health laboratories and with the CDC.

How much experience does the company have with environmental risk assessments and/or sampling for Legionella?

Phigenics has extensive experience performing environmental risk assessments and sampling for Legionella with facilities of all different types and sizes.
