Spore trap analysis
A spore trap captures particles from sampled air for microscopic examination. We connect the laboratory findings to where, when, and how that air was collected.
Inside the method
The cassette, microscope, and inspection each contribute a different part of the explanation.
01The collection
An air pump draws a measured volume through a collection cassette. Location, duration, and flow information help connect the sample to its reported concentration.
This is a sample of one place and time, rather than continuous monitoring.
02The microscope
The laboratory reviews the deposit directly under a microscope. Recognizable spores are reported in categories; some similar-looking groups cannot be separated by this method.
Direct examination does not require growing a culture and does not determine viability.
03The context
Indoor findings are considered with appropriate comparison samples, moisture observations, and the conditions of collection.
There is no universal federal airborne mold limit that turns a single count into a safe-or-unsafe verdict.
What to expect
We start with your concern, agree on the scope, and make the findings easier to understand.
Agree on the indoor-air question and appropriate comparison samples.
Document the sampling locations, air volume, and relevant conditions.
Explain the laboratory findings alongside the inspection observations.
Tell us about unusual activity, recent cleaning, ventilation changes, or prior sampling. We will explain any preparation appropriate to your sampling plan.
Reading the findings
Air sampling is the collection step. Spore trap analysis is a particular laboratory examination of material captured in a cassette. Other air-sampling methods can use different analyses.
Not for standard direct spore trap analysis. The collected deposit is examined microscopically. Culture analysis uses a different collection and laboratory process.
Some spores look similar under direct microscopy. The laboratory reports the level of identification the method supports rather than assuming a species.
No. Sampling should answer a useful question. We discuss what the inspection already tells us and whether an air sample would add relevant information.
The sample plan, requested analysis, and laboratory availability determine the cost and turnaround. We confirm the proposed scope, preparation, and expected timing before you proceed.
