The Swab test kit is intended for sampling surface biofilms.
Legionella grows in biofilms, therefore testing the surface of shower heads, air conditioning units, water tanks, taps etc. gives a very accurate picture of the condition of your water system. If Legionella is present, then the Swab test is very likely to detect it from the biofilm.
The test has been shown to be non-reactive with the following bacteria (at 1×108 organisms per sample):
Staphylococcus aureus and Legionella pneumophila serogroups 4 and 7 in samples at concentrations higher than 1×108 organisms per sample may produce weak positive results. These concentrations are higher than would be expected to be present in normal water samples.
Legionella pneumophila serogroups 4 & 7 cross react with the test at concentrations >109 CFU/sample. The test does not react with any other L. pneumophila serogroups or L. species tested.
A wide range of non-oxidizing biocides and bio dispersants have been checked for cross reaction and interference with the test.
The test should not be used on systems treated with biguanide or tetrakis hydroxymethyl phosphonium sulfate (THPS) based biocides
