Although Legionella lives in a wide variety of freshwater habitats, it can be difficult to isolate. The Environmental Legionella Isolation Techniques Evaluation (ELITE) Program was created as a way for laboratories to test their Legionella isolation techniques against standardized samples.
Q: What does it mean if the lab I am using is not on the ELITE Members List?
A: It depends on the reason for testing environmental samples for the presence of Legionella. If you need samples tested during an investigation into cases of disease, you should consider using an ELITE member laboratory. This will ensure that the laboratory understands the extra measures needed to secure an environmental isolate for public health investigations.
