The single syringe test kit is the most versatile technology for the rapid detection of Legionella bacteria in water samples taken from any source.

  • Fast results – as fast as 25 minutes
  • Any system anywhere
  • Easy to use
  • High sensitivity and reliable

The test contains all the items required to perform 1 test.

  • This test is designed for any water system such as hot and cold water systems, showers, industrial water systems (e.g. cooling towers) and domestic water systems.
  • The filtration step does not require any effort, and it allows the concentration of the Legionella bacteria to achieve a sensitivity of 100 CFU/L.
  • Pre-filled syringe containing recovery buffer, no need to measure or dilute solutions.
  • The test is simple to use, with no interpretation required.
  • Results are easy to read on site within 35 minutes.
  • Minimises delays and downtime.
  • Regular use increases confidence in your Legionella control.
  • App reader provides independent record of test.

The single syringe test kit uses an immunochromatographic assay to detect the presence of cell surface antigens from Legionella bacteria in a sample. The presence of antigen causes the “Test Line” to turn red in color. A “Control Line” is included which will always turn red if the test has been performed correctly.

Bacteria detected Legionella pneumophila serogroup
Detection method Lateral flow immunochromatographic assay
Lower limit of detection

As low as 100 CFU/L (0.1 CFU/mL)

Specificity

Tested against a wide range of waterbone bacteria, including: Acinetobacter calcoaceticus, Aeromonas hydrophila subsp. hydrophila, Bacillus subtilis, Burkholderia cepacia, Citrobacter freudii, Citrobacter koseri, Escherichia coli, Enterobacter cloacae, Klebsiella oxytoca, Pseudomonas aeruginosa, Pseudomonas fluorescens, Pseudomonas putida, Pseudomonas stutzeri, Ralstonia pickettii, Raoultella terrigena, Streptococcus pyrogenes, 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.

Legionella pneumophila serogroups 4 & 7 cross react with the Test at concentrations > 6×109 CFU/L. The test does not react with any other L. pneumophila serogroups or L. species tested.

Test volume 100 μL
Suggested sample volume 250 μL
Sample parameters

Sample should filter 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

At least 6 months from date supplied, when stored at room temperature (<30°C) in original packaging. All test strips are hermetically foil-wrapped with a printed expiry date
