Reliable self testing for Legionella

Legionella is a bacteria, which can cause a pneumonia-like disease called "Legionnaires' Disease". Legionnaires' Disease is fatal in approximately 20% of people infected. Infection occurs when the bacteria is inhaled from aerosols of contaminated water. Aerosols can be produced anywhere water is splashed or sprayed, but some of the most common sources associated with Legionnaires' Disease are cooling towers and showers.

Breakthrough technology for the rapid detection of legionella - Get accurate on-site results in 35 minutes

This innovative test kit allows the easy and quick testing of water; on-site and without training or experience.

  • Highly sensitive test
  • Fast & On-site
  • Kit includes everything required to carry out the test
  • Reliable & independent
  • Audit trail: log & report the results using the Hydrosense App
  • No training or expertise required
  • Because of its high sensitivity, it is recommended for higher risk industries and applications such as healthcare, hospitality, cooling towers, spa pools and others

How does the test work?

The Hydrosense test detects Legionella antigen using the well-established lateral flow test technology. The same technology is used in many medical tests. The test works just like a pregnancy test except it detects LpSG1 antigen. It works by attaching colour indicators to Legionella antibodies printed on a cellulose strip. This type of test is a specific type of lateral flow test.

What is a Lateral flow test: (LFT) technology has been in medicine for more than 30 years and is a standard type of test for hundreds of different uses: medical, environmental, food, beverage, veterinary and drug detection, amongst others.

Does it test for all Legionella bacteria? The test detects Legionella pneumophila serogroup 1 (LpSG1). With filtration step, the sensitivity of the water test is 100 CFU/L. The test detects Viable-But-Non-Culturable Bacteria and Legionella SG1 in all stages of its life-cycle.

Hydrosense App: Download the free reader app to store the results to provide an audit trail (only available for Iphones, more to be added at a later stage).

Suitable for: water collected from any source, industrial as well as domestic hot and cold water systems, including tap, shower, cooling tower, hot tub & pool, humidifier etc
Manual filtration enhances sensitivity

Bacteria detected: Legionella pneumophila serogroup 1
Sample Volume: 250 ml
Sensitivity: 100 cfu/l (0.2cfu/ml)
Contains: 1 Test
Total test time: approx. 35 minutes (about 10 minutes for filtering and 25 minute for the results to develop)

Shelf Life: usually 18 months from date of manufacture

MSDS only required for buffer solution. Please contact us to find out more.

Specificity:  Tested against a wide range of waterborne 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.

  • Organism / ≥cfu/mL: L.p Sg-2,3,8,11,13,14 / 1.00E+08; L.p. Sg-4,5,6,7,9,10,15 / 1.00E+07; L.p. Sg-12 / 8.00E+06; S.aureus / 2.00E+08

The Hydrosense legionella pneumophila Sg-1 test has been shown to produce weak positive results with other legionella pneumophila serogroups at the cfu/ml stated in the above list.

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.
