The control test should be a mold test kit left open on
ground outside
building and at least five feet beyond
drip edge of
room. Use
same time (thirty minutes to one hour) that was utilized in
indoor air tests for
settling method tests. There should be no rain or snow falling.
Self-Interpretation of Mold Test Kit Results
The tester can then either watch
test kits himself for mold growth, with self-interpretation of
mold test kit results, over a seven day time period, or send
mold test kit to
mold lab immediately, or after
self-observation growth period.
Here is how to self-interpret
visible mold growth in
mold test kits after seven days of mold growth---
1. If
tester observes and count a greater number of mold colonies of any particular mold colony type (possessing
same or similar color, shape and/or structural pattern) growing in one indoor mold test kit than in
outdoor control mold test kit, then
tester can reasonably decide that there is a possible indoor-generated mold infestation in
area/location involved in that particular mold test.
2. If
tester observes a particular mold colony type growing in a particular indoor mold test sample that is NOT present in
outdoor control mold test, then
tester can reasonably conclude that there is a possible indoor-generated mold infestation in
area/location in which he conducted that particular mold test.
3. If
tester observes three or more of
same mold colony type growing in one mold test kit, then
tester can reasonably conclude that there is a possible mold infestation in
area/location in which he conducted that particular mold test, regardless of
number of similar mold colonies present in
outdoor control test.
Why is that conclusion possible? Consider this rat analogy: if there are only three rats living inside a particular area of one’s home or building, is there no indoor rat problem just because there are more rats living immediately outside of
home or building?
It is
time-cumulative exposure and body intake of even modest numbers of indoor airborne mold spores that makes residents or occupants sick from mold exposure. Because residents or occupants spend many hours per day indoors in a home or workplace, they are continually inhaling or ingesting mold spores.
When
mold spores enter into
residents’ eyes, nasal/sinus areas, lungs, stomach (eating and drinking food and beverages upon which airborne mold spores have landed), or open body sores,
mold-spores, once inside
body, can begin dangerous mold growth inside
body because of
abundance of body moisture and food to eat (people’s bodies)!
4. If
tester observes three or more of
same mold colony types in several or many mold tests taken from different areas of
home or building,
tester can reasonably conclude that
mold species is possibly widespread in its contamination of
tested home or building.
The most dangerous mold species to residents and occupants are
molds that are omni-present through out
home or building, thus causing widespread, cumulative mold exposure and body intake. For more information about
use of mold test kits, mold laboratory analysis, and mold species identification, please visit---
