SINGLE TEST KIT
The Single Syringe test kit, is the most flexible kit in the Hydrosense range.

The filtration step concentrates the Legionella improving the sensitivity. It is designed for any hot and cold water system, showers and can be used in industrial water systems (e.g. cooling towers) and domestic water systems.

Legionella is a germ that can cause a severe type of pneumonia
(lung infection) called Legionnaires’ disease. Legionella can also
cause Pontiac fever, a milder illness without pneumonia. Make sure
disinfectants in hot tubs/spas (like chlorine) are kept at the level and
pH needed to reduce the risk of spreading germs like Legionella. If
you have symptoms of Legionnaires’ disease or Pontiac fever, such as
cough, shortness of breath, fever, or muscle aches, see your healthcare
provider right away. Be sure to tell your healthcare provider if you used a hot tub/spa in the last two weeks.

Legionella and Hot Tubs/Spas
Hot tubs/spas can spread Legionella
People can get Legionnaires’ disease or Pontiac fever when they breathe in small droplets of water (mist)
that contain Legionella. Legionella is found naturally in freshwater environments, like lakes and streams.
It becomes a health concern when it grows and spreads in human-made water systems. For example,
Legionella can grow and multiply in hot tubs/spas that are not disinfected and cleaned properly.
Legionella can also be found in other human-made water systems such as cooling towers, plumbing systems,
and decorative fountains.
People at risk
Certain groups of people are more likely to get
Legionnaires’ disease:
• People 50 years of age or older
• Current or former smokers
• People with chronic lung disease
• People who have health problems or take
medicines that lower their body’s ability to fight
germs and sickness—such as people whose
immune systems are weakened because of cancer,
an organ transplant, or HIV
Protect yourself and others
Below are steps you can take to test hot tub/ spa
water and find out if it is being properly maintained.
• Buy test strips at your local retailer or pool supply
store. Be sure to check the expiration date.
• Use the test strips to check these levels:
» Free chlorine level should be 3–10 parts per million
» Bromine level should be 4–8 parts per million
» pH should be 7.2–7.8
• Tell the hot tub/spa operator or owner if you find
improper chlorine or bromine levels or pH.
Questions to ask your hot tub/spa
operator
• What was the most recent health inspection score for
the hot tub/spa?
• Are the disinfectant levels and pH checked at least
twice per day?
• Are the disinfectant levels and pH checked more often
when the hot tub is being used by a lot of people
relative to its size?
• Are the following maintenance activities performed?
» Daily removal of the slime or biofilm layer by
scrubbing and cleaning
» Replacement of the hot tub/spa water filter
according to the manufacturer’s recommendations
» Replacement of hot tub/spa water as often as
required by the health department or recommended
by the manufacturer

Almost every regulatory framework in the world recommends the use of the Laboratory Culture method. This is principally due to the fact that technique has been around for a long time so is well understood.

However, the latest version of the ISO Water quality — Enumeration of LegionellaLab Culture standard (11731:2017) states that recovery rate of the laboratory test is “ > 64%”. Meaning that up to 35 out of every 100 samples tested even in an ISO accredited lab could produce a false negative result. In non-accredited labs this number is likely to be much higher. Hydrosense’s recovery rate is over 80%, 15% higher than that stated in the ISO document.

Additionally, the Lab Culture method is unable to detect Viable but Non-Culturable (VBNC) forms of Legionella bacteria which can still infect human lung cells. Hydrosense detects VBNC bacteria.

A positive Lab Culture result is a positive result two weeks too late – by the time the result is received people have been at risk of infection for two weeks. Conversely, a negative Lab Culture result provides a false sense of security as Legionella populations can double in 24 hours or less. A result from two weeks ago is a view of the past which holds little, if any, meaning for today. Hydrosense can provide results in 25 minutes, in fact, a positive result is sometimes visible much faster than that.

If your local regulatory compliance framework or water system circumstances dictate that lab testing is required, then you must carry out a lab test, in which case the Hydrosense test should not be used as a replacement. However, considering the factors mentioned above, it is unwise to use the lab culture method in isolation. Hydrosense recommends that more than one test method should be used (whether Lab Culture, Hydrosense or PCR) in order to effectively protect businesses, their employees, customers, and the general public from the risk of Legionnaires’ disease.

Our customers often use the Hydrosense test in addition to periodic lab culture tests and as a part of an overall risk assessment to minimise the risks of Legionella exposure.
