Mold Sampling

The main reasons for having mold testing performed in your home are:

  • You notice signs of mold such as a mold smell or mold symptoms
  • To identify the species of mold in your home
  • To help you find where mold is growing
  • To test indoor air quality by measuring the amount of spores in the air
  • To test if mold in your home has been fully removed

 

The three main types of mold tests are:

  • Air testing
  • Surface testing
  • Bulk testing

 

Air Testing for Mold

Air sampling tests the concentration of mold spores in your home’s air. Samples are taken from the air and are later examined under a microscope. Air tests can tell you if you have a mold problem even if you cannot find the mold growth. However, the amount of mold spores in the air can change drastically in a small amount of time, giving varying results at different times.

 

Surface Testing for Mold

Surface testing takes samples from household surfaces to find the amount of mold growth and spores deposited around the home. Samples are collected by swabbing, tape lifting or other methods. The sample is then examined in a laboratory.

Like with air testing the results can vary because mold growth and spores aren't spread evenly across surfaces in the home and can change over time. Unlike air testing though, surface tests can't identify the exact concentration of mold spores in the air.

 

Bulk Testing for Mold

Bulk testing involves collecting pieces of material from the home. The material is then taken to a laboratory where mold particles on the material can then be examined under a microscope. Bulk tests can tell you if you have a mold problem and give you an idea of the concentration of mold particles in your home.
