Mold Growth Test


This laboratory test measures concentration of mold spores on the surface of your sample. Please not that this is not a DIY or sampling kit, and you need to bring or send your sample to our laboratory in London, Ontario, Canada.

During the test we collect mold spore and hyphal from the surface of your sample and stain them with lactophenol blue. We identify 12 types of mold and measure their concentration on the surface. The results can be used for assessment of water damage or identify potential source of allergies. The fee includes laboratory analysis and formal report, which will be sent to you by email.

To proceed with the order, pleas select number of samples that you are planning to test, and the turnaround time. Please remember to check the shipping instructions tab.



Once we receive your samples, we test them in our laboratory in London, Ontario, and report you mold concentration on the surface of your sample and what types of mold spores are present. Your report will show individual concentrations of 12 types of mold:

Stachybotrys/Memnoniella (Black Mold)
Hyphal fragments

If you have any questions, please email us at your convenience

Cut a small piece of mold stained paint, wood, paper, plastic, or plaster, and place it in a Ziploc bag. You need only 1/4 square inch of material, which is about the size of a coin. It does not have to be exact amount, but we need a piece with  some flat area to work with.  Label the bag with a permanent marker: “Ceiling paint from kids’ bedroom”, or “Yellow flooring from kitchen”. If you want to test more than one sample, each sample should be placed in a separate bag. Please take as many samples as you need, but please label each bag.
