Legionella Testing & Analysis
Comprehensive Legionella testing and analysis services to detect bacteria in water systems, mitigate risk, and protect public health. Don't react to what's in your water — respond.
Why Test for Legionella?
Legionella bacteria can pose serious health risks, especially in environments with large plumbing systems, cooling towers, and water features. The bacteria can cause Legionnaires' disease — a severe form of pneumonia — as well as Pontiac fever. These illnesses can be fatal, particularly for individuals with compromised immune systems.
Routine monitoring is the keystone to outbreak prevention. Legionella testing helps organizations achieve critical goals:
Regulatory Compliance
Meet ASHRAE 188, state, and federal requirements for water management and Legionella monitoring in healthcare and commercial facilities.
Water Safety Validation
Validate your water safety management plan with routine testing to confirm your control measures are working effectively.
Reputation Management
Protect your organization, employees, and customers from preventable diseases while mitigating business risks.
Legionella Testing Methods
Legionella ISO Culture
TAT: 7 daysThe ISO 11731 culture method is the gold standard for Legionella testing. It follows the International Organization for Standardization's protocols for detecting and enumerating both Legionella pneumophila and non-pneumophila species. Capable of detecting 20 species including 16 serogroups of L. pneumophila.
Best for: Compliance, baseline testing, outbreak forensics
Legionella CDC Culture
TAT: 7 daysThe CDC culture method can identify all Legionella species and serogroups, providing isolates for detailed analyses like source tracking. Required for compliance in some jurisdictions.
Best for: Compliance, baseline testing, outbreak forensics
Legionella qPCR
TAT: 1-2 daysQuantitative polymerase chain reaction (qPCR) is a rapid method that detects Legionella species in both drinking and non-drinking water samples. Often paired with culture methods for comprehensive outbreak analysis.
Best for: Rapid screening, time-constrained investigations
Legiolert
TAT: 7 daysAn easy-to-use culture test specifically for Legionella pneumophila — the species responsible for the majority of Legionnaires' disease incidents. Requires minimal technical skills to perform and results are easy to interpret.
Best for: Baseline testing, water management validation
