Legiolert: Legionella pneumophila

Scope Legiolert for legionella pneumophila. Define sample matrix, preparation, reporting limits and project requirements.

Legionella pneumophila measurement context

Legiolert, a culture test with an enzyme substrate: Legionella pneumophila grows in the medium and breaks down a substrate, giving a brown color or turbidity, and the result is a most probable number per volume tested. The test detects Legionella pneumophila only, not other Legionella species.

Plan collection and receipt together

Define the organism or indicator, test portion and enumeration or presence/absence question. Use the assigned bottle and collection instructions and coordinate delivery around the method requirements.

Include the complete project requirement

Provide the matrix, target analytes, required method, fraction, units and reporting limits. Include the permit or monitoring instructions where results will support a regulatory submission. Naming this method does not establish blanket compliance eligibility.

Resolve collection before sampling

Use the bottle, preservation and delivery instructions assigned to the agreed scope. Identify each location and collection time, and document any deviation. The final analytical plan must fit the submitted material and its intended use.
