Legionella Field Test Kit

Order Code: 7-2100

7 21001This kit is designed to test for Legionella in risk areas identified by CDC* such as:

  • Domestic and industrial hot and cold water systems
  • Pools, hot tubs and decorative fountains
  • Cooling towers
  • Sinks and showers
  • Misters, sprinklers, air washers, humidifiers and others

The Legionella Field Test™ uses Lateral Flow Immunochromatographic Assay (LFICA) technology to detect the presence of cell surface antigens from Legionella bacteria. 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.



Legionella Field Test Kit

Bacteria detected Legionella pneumophila serogroup 1
Detection method Lateral flow immunochromatographic assay
Lower limit of detection As low as 100 CFU/L (0.1 CFU/mL)

Tested against a wide range of waterborne bacteria, including Acinetobacter calcoaceticus, Aeromonas hydrophila subsp. hydrophila, Bacillus subtilis, Burkholderia cepacia, Citrobacter freundii, Citrobacter koseri, Escherichia coli, Enterobacter cloacae, Klebsiella oxytoca, Pseudomonas aeruginosa, Pseudomonas fluorescens, Pseudomonas putida, Pseudomonas
stutzeri, Ralstonia pickettii, Raoultella terrigena, Streptococcus pyogenes, Yersinia ruckeri.
No cross reactions have been observed at concentrations ≤ 109 CFU/L. Staphylococcus aureus has been observed to cross-react with the test at concentrations > 108 CFU/L, which is higher than found in most water samples.

The Legionella pneumophila SG1 test has been shown to produce weak positive results with other legionella pneumophila serogroups at the cfu/mL stated in the above table.

Test volume 100 μL
Suggested sample volume 250 mL
Sample parameters Sample should fi lter in less than 10 minutes.
Biocides The product has been tested with a range of common biocides and biodispersants used in
Legionella control, at their normal maximum operating concentration. Active ingredients
tested include: glutaraldehyde, dodecyl-dimethyl-ammonium chloride, isolthazoles,
dibromonitrilopropionamide, ionic and non-ionic surfactants. The Test gives a false positive if used with polymeric biguanide or THPS. It should not be used to test such systems.
Operator time 5–10 minutes
Test time 25 minutes
Shelf life 18 months from date of manufacture, when stored at room temperature (<30°C) in original
packaging. All test strips are hermetically foil-wrapped and with a printed expiration date.
