How mycotoxins can remainon surfaces.
Mycotoxins are toxic chemical compounds produced by certain molds under specific conditions. Because they can associate with dust, fine particles, and materials, they may settle or remain on surfaces inside the home.
Particles can carry them
Mycotoxins may associate with dust, fragments, and other fine particles that move through the indoor environment.
Surfaces can hold residue
Once deposited, mold-produced toxins may remain on surfaces, porous materials, or items even after visible mold is no longer present.
When mycotoxin surface testing is the right fit
MESA™ is designed for targeted surface questions — when you want to evaluate whether mold-produced toxins may be present on a specific surface, material, item, or area.

A short explainer on how MESA™ evaluates targeted indoor surfaces, belongings, and materials for mold-produced toxins.
Where to take a mycotoxin surface sample.
Drywall
One of the most reliable surfaces for detecting mycotoxins — porous and slow to release contamination.
Frequently touched surfaces
Walls, door frames, shelving, and high-contact areas indicate ongoing contact exposure risk.
Furniture & belongings
After water damage or mold exposure, testing helps decide whether items are safe to keep, clean, or remove.
Post-remediation areas
Swabbing previously affected zones confirms whether mycotoxins were removed alongside the visible mold.
HVAC components
Return vents and accessible duct surfaces reveal whether mycotoxins are circulating through the building.
Areas of concern
Any surface near odors, staining, or past moisture issues that may harbor lingering contamination.
Dust tells one story. Surfaces tell another
Dust testing helps evaluate what has accumulated over time. Surface testing helps evaluate a specific surface, material, or item. Both can be useful — they just answer different questions.

MESA screens for key mold-produced toxins
The standard MESA™ panel includes 7 mycotoxins across major toxin groups. An extended panel is available when additional targets are needed.

Mycotoxin surface test FAQs
A mycotoxin surface test measures mycotoxins present on building materials, furnishings, or household surfaces. It helps identify toxin contamination that may remain after mold growth, water damage, or remediation.
Surface mycotoxin testing collects samples directly from a specific location, such as drywall, furniture, or HVAC components. Dust testing analyzes mixed settled dust, which may not reflect where contamination is originating or persisting.
Surface samples are commonly collected from drywall, frequently touched surfaces, furniture, HVAC components, post-remediation areas, or any location associated with water damage, odors, or suspected contamination.
Yes. Surface mycotoxin testing is often used after remediation to help determine whether mycotoxins remain on treated materials, even when visible mold has been removed.
Yes. Surface testing can help assess whether mycotoxins are present on items like furniture, clothing, or personal belongings, providing insight into whether cleaning efforts were effective or if replacement may be necessary.
Mycotoxins present on surfaces may become airborne when disturbed by airflow, HVAC operation, cleaning, or everyday activity, which can contribute to indoor air exposure.

Let's confirmyour surfaces after mold
Removing visible mold is only part of the process. Surface testing helps verify whether mycotoxins were removed from indoor surfaces after remediation is complete.
