Mold testing, or what we call “sampling,” is a standard part of most mold assessments. However, you are not required to get testing during an assessment. Testing is often needed for diagnostic purposes. There are several different methods we use at Texas Mold Consultants. A few common methods include:

  • Ambient air sampling
  • Wall cavity sampling 
  • Tape slide sampling
  • Mold sampling

Air Sampling

DETECTING MOLD VIA COMPOSITION OF INDOOR AIR

This is a measurement of what is present in the air in a certain area at that moment in time. We use a calibrated air pump to sample for five minutes. The pump sucks in 75 liters of air to be sampled. We use Allergenco-D air sampling cassettes, which collect mold spores for laboratory analysis. The cassette is sealed and delivered to a State Mold Licensed lab where the genus and concentration of spores in the air are determined. An outdoor reference sample is always obtained for a baseline comparison to the indoor samples.

Wall Cavity Sampling

MOLD TESTING TO FIND SPORES IN HIDDEN AREAS OF THE HOME OR BUSINESS

This is used as a diagnostic tool to determine what microbial activity is present in the space behind a wall. We start by drilling a half-inch hole through the sheet rock. Then we attach a specialized tube adapter to the Allergenco-D cassette. The end of the tube is then inserted into the wall cavity. A small rubber grommet on the tubing seals the hole and ensures a depth of approximately two inches. A two-minute sampling time is used to test the cavity space. Cavity air sampling can detect mold in a wall where there is no outward indication of water or mold damage!

Tape Slide Samples

GETTING SPORE SAMPLES BY DIRECT INSTRUMENT CONTACT

These are used to obtain samples of fungal spores and other particles by making direct physical contact with a surface. The tape slide is a plastic slide with an adhesive surface that is pressed against the material to collect the desired sample. As with air samples, the tape slides are sealed and delivered to a State Mold Licensed lab for identification of fungal spores and mycelial fragments. The results consist of the genus of the spores and whether they're in a growth or non-growth status.
