Most Common Sampling For Mold

Air Sampling:

Nonviable samples are those that cannot be grown into colony forming units and this process of lab analysis usually takes between 1-3 days to complete.

Air Samples consist of three basic impaction mediums: culture plate (usually potato dextrose), standard impact,  and cassette impaction. These will help determine the level of bio-aereosols.

It is important to note that it is always advisable to take both an outdoor and an indoor air pre remediation and post remediation to have a comparative basis to analyze regarding project closure.

Bulk Sampling:

Bulk samples are typically a 2 x 2 inch piece of material with mold growing on it that is cut from its surroundings.


Viable Culture Sampling:

Viable Samples are samples of live mold that can be grown in a culture plate usualy on a potato dextrose agar and it normally taken 1-1.5 weeks to complete this process.


Tape Lift Sampling:

Tape samples are a tapelike sticky material that is pressed onto the surface of the visible mold and then onto a plate for microscopy.


Swap Mold Sampling:

Swab samples use a Q-tip like instrument to swab against the visible mold. The moldy swap sample is placed in a test tube like instrument and sent to the lab for analysis.

Mold Sampling

There are a variety of means to conduct sampling. Viable, nonviable, bulk, swab, tape, and scraped samples are physical samples. Water samples typically test for bacteria levels due, for example, to sewage influx. The final category are air samples.
