OnSite Legionella Testing’s Direct Water Test uses Lateral Flow Immunochromatographic Assay (LFICA) technology to detect the presence of cell surface antigens from Legionellabacteria. It uses Legionella antibodies, tagged with red nanoparticles, which bind to any bacteria found in the sample and make them visible on a line on the device. The test works just like a pregnancy test – one line indicates a negative result and two lines indicate a positive result.

Alternative versions of the test for specialist applications are also available.
