- Air Sampling
Air samples test for viable (living) black mold. Mold
Sampling and Testing for viable mold is done by placing
the sample onto agar culture medium that supports
the growth of the organism(s) in question and allows
identification of the species and level of contamination.
When colonization occurs one black mold has overtaken
your entire home. Colonization
is the formation of compact population groups of the
same type of black mold and mildew species.
Air samples also test for nonviable (dead) black mold.
Mold Testing for nonviable mold is done by microscopic
examination of the sample to identify fungal and non-fungal
particles that may be allergenic to individuals.
- Bulk Sampling
Bulk samples include, but are not limited to, chunks
of carpet, insulation, and wallboards. Bulk samples
are collected from visibly moldy surfaces by scraping
or cutting materials with a clean tool and placing
the sample into a petri dish mold sampling and for
testing.
- Surface Sampling
Surface samples are collected by wiping a measured
area with a sterile swab or by lifting a sample with
bio tape. The surface sample is cultured and then
placed into a petri dish. After allowing 3 - 7 days
for the samples to show visible fungal growth, the
petri dish is inspected by a lab technician under
a microscope so that the fungi can be removed and
identified by species.

Mold Sampling and
Testing is necessary where:
|
| |
- Health concerns are a problem
- Litigation is involved
- The source(s) of the mold
contamination is unclear
