Mycotoxins Testing
A successful mold remediation removes the colony. It doesn’t remove what the colony produced. Mycotoxins — the toxic chemical compounds certain mold species generate — accumulate in dust, settle into building materials, and persist in a structure indefinitely. Standard spore counts won’t detect them. This test will.
OVERVIEW
The Mold Is Gone.What It Left Behind May Not Be.
Mold spores are what most testing is designed to find. Mycotoxins are something different entirely — they are chemical byproducts of mold metabolism, produced by certain species as the colony grows. Stachybotrys, Aspergillus, Penicillium, and Fusarium are among the most common indoor species known to produce them. Once produced, mycotoxins do not behave like spores. They don't float freely through air at detectable concentrations. They bind to particles, embed in dust, and absorb into porous materials — walls, insulation, carpeting, wood framing — where they remain active and harmful long after the mold itself has been addressed.
This is the gap that mycotoxin testing fills. If your property has a mold history, if occupants are experiencing symptoms that don't resolve after remediation, or if you need documented evidence of what a structure actually contains — not just whether spores are present in the air today — mycotoxin testing provides the answers that a standard report was never designed to give you.
WHY STANDARD CLEARANCE TESTING DOESN'T COVER THIS
Post-remediation clearance testing confirms that airborne spore levels have returned to acceptable ranges. It is not designed to detect mycotoxins, which settle out of the air and accumulate in dust and materials. A building can pass clearance testing completely while still carrying significant mycotoxin contamination — because clearance testing is asking a different question.

WHO IS THIS FOR
This Test Is the Right Next Step If...
REMEDIATION PASSED —
SYMPTOMS DIDN'T CLEAR
Clearance testing confirmed the mold was removed, but occupants are still experiencing fatigue, cognitive difficulty, or respiratory issues. Mycotoxin residue is one of the most common explanations.
A PHYSICIAN HAS FLAGGED POSSIBLE MYCOTOXIN EXPOSURE
Your doctor needs environmental documentation to correlate health findings with building conditions. A mycotoxin report provides the lab-backed evidence that clinical testing alone cannot establish.
THE PROPERTY HAS A SIGNIFICANT WATER OR MOLD HISTORY
Repeated moisture events or long-term hidden mold growth leave a mycotoxin burden that accumulates in dust and materials over time — independent of whether active mold is currently present.
BUYING OR SELLING A PROPERTY WITH A MOLD PAST
A mycotoxin report creates a documented baseline. It protects buyers from inheriting contamination that wasn't disclosed and protects sellers from future liability claims over what was present at sale.
OCCUPANTS INCLUDE CHILDREN OR IMMUNOCOMPROMISED INDIVIDUALS
Higher-risk occupants require a higher standard of environmental verification. When the margin for error is smaller, standard spore counts are not sufficient documentation.
YOU'VE HAD NORMAL TEST RESULTS BUT THE PROBLEM STILL FEELS REAL
Standard testing has a defined scope. Mycotoxin testing looks at what falls outside that scope. If your instincts don't match the report, there is likely a reason — and this is where to look.
OUR PROCESS
How We Conduct Mycotoxins Testing
1
History & Symptom Intake
Before any samples are collected, we document the full picture — prior water damage events, any previous mold testing or remediation reports, how long the property has been occupied, and the specific health symptoms occupants have reported. The pattern of symptoms matters: when they occur, which rooms are worse, whether they improve away from the property. This context determines which areas we prioritize and which mycotoxin panels are most clinically relevant to request from the laboratory.
2
Targeted Site Assessment
We conduct a focused walkthrough of the property with the specific objective of identifying where mycotoxin accumulation is most likely — HVAC return vents and air handlers where dust concentrates, horizontal surfaces with undisturbed settled dust, areas with documented moisture history, and any materials identified as potentially contaminated in prior reports. We are not conducting a general inspection at this stage — we are building a sampling map informed by the intake history.
3
Multi-Matrix Sample Collection
Mycotoxin testing requires samples from the right locations and the right materials — not just air. We collect settled dust from HVAC return grilles and horizontal surfaces, which captures what has accumulated over time rather than what is airborne at one moment. Surface swabs from areas of concern and bulk material samples from carpeting or insulation are collected where indicated. Each sample type answers a different question: dust samples reflect the building’s contamination history; surface and bulk samples reveal what has absorbed into specific materials.
4
Mycotoxin-Specific Laboratory Analysis
Samples are submitted to an accredited laboratory for mycotoxin-specific panels — this is distinct from a standard mold lab report. Analysis identifies specific compounds including trichothecenes, aflatoxins, ochratoxins, gliotoxins, and satratoxins, among others, and quantifies their concentrations. Where dust samples are collected, ERMI scoring provides a standardized measure of cumulative mold burden that can be compared across properties and referenced against EPA-established thresholds. These are specialized analyses that require specific methodology — they are not included in routine environmental testing.
5
Results Briefing in Plain Language
Laboratory results for mycotoxin panels are technical and require interpretation in the context of the full site assessment. We review every finding with you — which compounds were detected, at what concentrations, in which locations, and what those levels indicate about the contamination history of the structure. We do not deliver a report and leave you to interpret the numbers alone. You will understand what was found, where it came from, and what it means before we make any recommendations.
6
Written Documentation & Recommended Protocol
You receive a complete written report — laboratory results, ERMI scores where applicable, site assessment findings, and a recommended protocol specifying exactly what remediation or treatment is indicated based on what was found. This document is formatted for use in medical consultations, insurance claims, legal proceedings, and real estate transactions. If remediation is carried out based on the findings, post-work mycotoxin sampling confirms the environment has been restored to acceptable levels.
CLIENT REVIEWS
What Our Clients Say
“We had mold remediated twice in two years and kept getting sick. Our doctor suspected mycotoxins but no one could give us documented proof. FPT ran the testing, found trichothecene contamination in our HVAC dust that two previous reports had completely missed, and gave us a report our physician could actually work with. It changed the entire direction of our treatment.”

“I was purchasing a commercial property with a documented mold history. The seller had clearance reports but I needed to know what the building was actually carrying. FPT’s mycotoxin testing found residual contamination in the insulation that clearance testing wasn’t designed to catch. That report saved me from a very expensive mistake.”

FREQUENTLY ASKED QUESTIONS
Common Questions About Mycotoxins Testing
What are mycotoxins and how are they different from mold spores?
Mold spores are the reproductive particles mold uses to spread — they are what standard air sampling counts. Mycotoxins are toxic chemical compounds that certain mold species produce as part of their metabolic activity. They are not alive, they don’t disperse the way spores do, and standard air sampling is not designed to detect them. Mycotoxins bind to dust particles, penetrate porous materials like drywall and insulation, and remain present — and harmful — in a building long after all live mold has been removed.
My mold remediation passed clearance testing. Why would I still need mycotoxin testing?
Clearance testing confirms that airborne spore levels have returned to acceptable ranges — it verifies that the mold colony was removed. It does not test for mycotoxins. The two tests are measuring entirely different things. A building can pass clearance testing completely while still carrying significant mycotoxin contamination in settled dust, HVAC components, and building materials — because those compounds were never part of what clearance testing is designed to measure.
What health symptoms are associated with mycotoxin exposure?
Reported symptoms include chronic fatigue, cognitive difficulty or brain fog, recurring respiratory irritation, persistent headaches, joint pain, skin irritation, and immune dysregulation. These symptoms are non-specific — they overlap with many other conditions — which is exactly why environmental documentation matters. We are not in a position to diagnose or treat medical conditions, but a mycotoxin report provides the documented environmental data your physician needs to evaluate whether building exposure is a contributing factor.
Can mycotoxin contamination be remediated?
Yes — but the approach depends on which compounds were found and what materials they have penetrated. Contamination concentrated in HVAC systems is often addressable through deep cleaning and component treatment. Mycotoxins that have absorbed into drywall, insulation, or subfloor materials typically require those materials to be removed. The written protocol we provide specifies the exact scope of work based on the lab findings — there is no standard package because the contamination profile of every property is different.
Can this report be used for medical, legal, or real estate purposes?
Yes. The documentation we produce — third-party accredited lab results, ERMI scores where applicable, site assessment findings, and written remediation protocol — is formatted for use in medical consultations, insurance claims, legal proceedings, and real estate transactions. If you are building an environmental exposure case, evaluating a property purchase, or providing evidence to a physician, this report is designed to serve those purposes.
