On-Site Legionella Testing
Identify Issues Before They Become Problems
Potentially fatal Legionnaire’s disease is a significant public health risk and a hazard to your operations if left unmitigated. Multiple government entities mandate Legionella levels remain below a predefined limit.
Ensure your entire system is under control and alleviate risk. Safeguard the commercial cooling systems in your production facilities with LuminUltra’s microbial testing solutions.
Access a Rapid, Targeted Approach to Testing
- Quickly Investigate Risk
Know if Legionella is present in 90 minutes with accurate, on-site qPCR testing.
- Detect High-Exposure Areas
Determine perilous areas of Legionella contamination in minutes with on-site ATP.
- Identify Problems Early
Be alerted to a spike in bacterial growth and know about the biofilm development before it contains Legionella.
- Verify Treatment Efficacy
Make sure your biocide approach is effective by testing the sample location before and after treatment.
Know Where Legionella Is Found
In addition to being present in natural freshwater systems, Legionella also establishes itself in the engineered water systems of commercial and residential buildings. It colonizes in water systems operating at slightly above room temperature.
The most common places for Legionella growth is in heating, ventilation, and air-conditioning systems. These systems offer water slightly warmer than room temperature, and distribute any aerosolized Legionella bacteria.
Biofilm: The Ideal Living Conditions
Legionella cells cannot proliferate on their own; they require a biofilm of other microbes to grow and reproduce. Legionella are parasites – they can grow within other organisms present in water systems. Learn more in our Primer on Legionella.
Biofilm, a slime formed inside tanks and pipes, offers ideal living conditions and protects the Legionella from treatment. When sufficient Legionella have accumulated, it breaks out of the biofilm and enters the flowing water supply. As a result, it is present in aerosols from showers and taps and inhaled by unsuspecting people in the building.
qPCR Testing for Legionella
qPCR testing is a rapid, effective method for monitoring specific microorganisms, including Legionella. This approach offers many advantages.
- Make better decisions faster. Get results in under two hours of sample collection.
- Detect viable but non-culturable cells. Our highly sensitive tests identify potential issues before they become problems.
- A versatile solution. Test multiple samples with a range of assays in a single run, whether you’re in the field or in a lab.
A complete testing work flow
By combining our gold-standard qPCR analysis with a routine growth monitoring tool like 2nd Generation ATP®, you can take control of the microbes in your environment to reduce risk for your people, equipment, and business.
1. Routinely monitor growth in high-risk areas
2nd Generation ATP® alerts you to increases in overall microbial levels in minutes, as opposed to the days required for HPC or dip slides. Use 2nd Generation ATP® testing to map out the system and detect problem areas, then routinely to catch increases in microbial levels before they become a problem.
2. Identify the Legionella bacteria and eliminate it
Any areas with increased microbes can easily be tested with a GeneCount® qPCR test to determine presence of Legionella. Once treatment is complete, re-test to verify its efficacy.
Quicker corrective actions lead to reduced remediation costs and lower risks. Testing fluids and surfaces with a combination of ATP and qPCR gives you the maximum capability to identify, quantify, confirm the treatment of, and monitor for the regrowth of both Legionella and microbiological populations.
