How Rapid Legionella Testing Works

LegionellaFast uses a Lateral Flow Immunochromatographic Assay (LFICA) to detect the presence of cell surface antigens from Legionella pneumophila serogroup 1* in only 25 minutes.

Once suitably filtered, the presence of the antigen in a water sample causes the “Test Line” to turn red in colour. A “Control Line” is also included which should always turn red if the test has been performed correctly.

How to use LegionellaFast self-test procedure 

LegionellaFast has been designed to test waters to a sensitivity of 100 CFU/L making it ideal when access to a legionella laboratory is impractical or speed is imperative.

LegionellaFast should be used to support your existing legionella risk management procedures and sampling programme and should not replace routine laboratory analysis.
