Overview
Within a water system Legionella usually grow within biolm (slime) found on the insides of pipe work, shower
heads, cooling tower packing, or water tanks. Bacteria found in the planktonic phase (i.e. suspended in the
water itself) are usually an indicator of colonization of the biolm.
Since a clean water sample does not equate to a clean system (proliferation of legionella is greater in a biolm
than in water), this kit can be used to pinpoint the contamination in a system or to demonstrate cleanliness of
an area after a targeted
cleaning. The test operates via a Lateral Flow Immuno-Chromatographic Assay (LFICA).

This test is intended for analysis of biolm samples only. This product is not intended for clinical or medical
diagnostic use.
The product is intended to be used as part of an overall water treatment, management, and risk reduction
approach and should NOT be used as the sole method for assessing risks associated with Legionella bacteria.

Performance of the Swab Test Kit with samples other than those taken from Cooling Towers, Domestic Hot &
Cold water systems and Whirlpool spas has not been established.
Disposal
The test cannot be reused or recycled. The packaging materials and this instruction manual can be recycled.
Storage
The test is intended for storage at room temperature. Do Not Freeze. When stored correctly, the test will
