# How To Take Mold Samples Training Course

## Mold Samples

Mold test results are only as good as the sampling procedure. Some of the mistakes mold inspectors make include submitting inadequate samples, submitting inappropriate samples, or collecting samples wrongly. Results from such samples are difficult to interpret. In this course you'll learn how to correctly take mold samples.

There are a variety of samples one can collect during a mold inspection. These include air (viable and nonviable), bulk, swab, tape, and surface scraped samples.

• Viable air samples are collected in agar dishes containing malt extract agar (MEA). These samples require culturing and normally taken 7-15 days for the lab to finish the analysis and reporting.
• Nonviable air samples are collected in cassettes such as Air-O-Cell, Allergenco D or similar other cassettes. These samples do not require culturing and the analysis takes between 1-3 days to complete.
• Bulk samples are typically pieces of material with mold growing on them that are cut from contaminated building materials.
• Tape samples are collected by sticking clear scotch tape onto the surface of the visible mold. These samples are not cultured and therefore can be analyzed within 1-3 business days.
• Swab samples, as the name suggest are collected using swabs. These samples can be analyzed by direct microscopic examination or by culturing. We do not recommend use of Q-tips because they are normally not sterile.
• Surface scraped samples are literally scraped from the moldy material and bagged and properly labeled for lab analysis.

It is important to note that it is always advisable to take both an outdoor and an indoor air to have a comparation during mold results interpretation.
