Frequently Asked Questions

How does the test work?

Our team of scientists has devised and developed the Water Test range by simplifying the protocol applied in the laboratory.

You simply need to take a water sample and follow the step-by-step procedure shown on the accompanying instruction leaflet. After 30 minutes of handling operations on the first day, the sample is left to incubate for 48h. This is the necessary and incompressible time needed to reveal whether or not pathogenic bacteria are present. At the end of this waiting time, 40 minutes of operation is still necessary in order to obtain the result.

As for a pregnancy test, the Legionella Water Test functions with a strip which makes a result appear:

– 1 red line, the test is negative

– 2 red lines, the test is positive

If the result is positive, this indicates a Legionella pneumophila concentration greater than or equal to 10 CFU / mL (Colony Forming Units per millilitre of water), which is potentially hazardous to health.  

Why do you have to wait 48h to obtain the result?

The reliability of the results of the Legionella Water Test is based on the incubation of the bacteria at a constant and homogeneous temperature for 47h in the incubator provided in the Mini-Lab. This is the minimum time necessary to reveal the presence of pathogenic bacteria. This is the same technique as the one used in the laboratory which generally takes 10 to 12 days.

Is the Refill test kit reusable?

No, each Refill test kit is for single use and is valid for one single test.

Can I use this kit to test bathing water?

Yes. The Water Test range is devised to test all water, including bathing water.However, legionellae are absent from sea water. Only the Coliforms Water Test can be used to test sea water.
