Overview

test image Laboratories can test their Legionella isolation techniques against standardized samples through the Environmental Legionella Isolation Techniques Evaluation Program. Participating labs receive a panel of lyophilized test samples twice each year from the Wisconsin State Laboratory of Hygiene. Some of the test samples are Legionella positive and some are Legionella negative. The test samples may also include other organisms commonly found in water. Participating labs process the test samples and report their results. Those labs that correctly identify Legionella in 2 consecutive panels receive documentation for passing the proficiency test. Labs can check their status by logging in.
