Legionella Test






In aerosols generated by a shower head of a hospital or a hotel, in a car wash or in an industrial cooling system, there may be water droplets brimming with bacteria. This is how Legionella reaches us, through inhalation. Legionella sp. can travel huge distances. Cases of infection have been reported in a radius of up to 10 km away from the source. Near or far, if Legionella reaches our lungs it will behave in a very similar way, either colonizing or invading. In a few days pneumonia will develop. Legionellosis is a systemic infectious disease that primarily affects the lungs and has a mortality rate between 5% and 30%. Of the total cases reported, 95-98% can be attributed to Legionella pneumophila. This disease is a hot topic in the field of Public Health, as its average mortality rate is 12%-15% and it can easily reach 30-50% in patients with weak immune systems or who do not receive antibiotics promptly.

Current standard recommended Legionella test is based on a cultural method, needing up to 2 weeks for Legionella bacteria to grow and to be counted which is far too long to take action and to prevent danger. The new Legipid® test is based on a patented, immunomagnetic method, detecting only living Legionella sp. As tests develops a readable color, it now got adapted on the PrimeLab 1.0 multitest photometer.

Whilst the common cultural method needs an agar on which legionella have to grow to be counted after several days, Legipid® works differently. 1 litre of sample water is filtered to concentrate Legionella on a filter paper. Legionella on filter paper gets released in a small vial where “L1″ is added. “L1″ is a patented solution, containing immuno-magnetic particles (antibodies), only attaching to living Legionella sp. After several washing steps, a colouring solution is added to colour the captured Legionella. Concentration of the colour is in relation to concentration of Legionella in the sample which makes it possible to be tested by the PrimeLab 1.0. Result is displayed as cfu per test.

Legipid® test kit comes with all you need to run Legionella tests, apart from the PrimeLab plastic adapter for 1ml vials and a filter kit to filter your water sample.


For all those who currently use a PrimeLab, all you need, is an update through the PrimeLab Desktop Assistant Software or the App, an activation code for ID 147 (Legionella) and a small plastic adapter to use 1ml Legionella vials. If you do not yet have a PrimeLab, it benefits from more than 120 different test methods, starting with A for Alkalinity to Z for Zinc. JENCOLOR sensor technology allows parallel testing on 400 different wavelengths ensuring outmost accuracy of test results.
Wireless bluetooth technology, free software and App, individual parameter setup, free cloud service, dosage recommendations based on your individual water treatment chemicals, activation of more parameters at any time, reports per account (test sources), Turbidity (NTU) along with PTSA and Fluorescein by adapter… to name just a few of the benefits of the PrimeLab 1.0 Multitest photometer.

High-risk facilities

registered in Europe and between 8,000 and 18,000 people are hospitalized in the USA.
Mortality rate figures range from 6% to 15% every year, likely to be an underestimation, since many countries are unable to provide mortality figures.

  • High-risk facilities include:
  •  Cooling towers and evaporative condensers
  • Hot water systems with water tanks and return circuits
  • Heated water systems with recirculation through high speed water jets or air injection
  • Industrial humidifiers
  • Internal systems for cold water intended for human consumption (pipes, water tanks,cisterns or mobile tanks)
  • Hot water systems without a return circuit
  • Evaporative cooling equipment which sprays water
  • Humidifiers
  • Ornamental fountains
  • Sprinkler water systems in urban environments
  • Fire extinguishing systems that uses water
  • Outdoor aerosol equipment that uses water
  • Other devices that store water and produce aerosols
  • Respiratory therapy equipment
  • Respirators
  • Nebulisers
