Environmental samples and building-focused investigation
Mycotoxin Testing Connected to Mold, Moisture and the Sampled Environment
Angstrom Testing Services LLC provides environmental mycotoxin testing and mold-related building assessments for homes, apartments, condominiums, cooperative buildings, offices, schools, health care facilities, commercial properties, property managers, attorneys and building owners.
Depending on the project, testing may include selected settled-dust samples, surface samples or pieces of visibly moldy and water-damaged material. The environmental assessment may also include a review of the water-damage history, visual inspection, moisture measurements, odor observations, HVAC review and other mold sampling.
Environmental mycotoxin testing is different from urine, blood, sputum or other clinical testing. Angstrom collects and interprets environmental samples only. Medical testing and health-related interpretation should be handled by qualified health care professionals.
A specialized environmental measurement
A Laboratory Result Must Be Connected to the Building
A mycotoxin result represents the selected sample, location and material collected at the time of the assessment. It should be reviewed with the moisture history, visible mold, damaged materials, dust age, cleaning history, HVAC conditions and reason the sample was collected.

Common environmental project objectives
When Mycotoxin-Related Testing May Be Considered
Not every mold concern requires mycotoxin analysis. Specialized testing is most useful when the sample locations and analytical method address a defined environmental question.
Hidden Mold Concerns
Musty odors, concealed water damage or conditions behind walls, flooring, ceilings and cabinets may warrant further investigation.
Historical Water Damage
Repeated leaks, flooding, roof failures, plumbing incidents or incomplete drying may leave damaged materials and dust reservoirs.
Settled-Dust Concerns
Dust sampling may be considered where historical deposition, older furnishings, carpeting or room-specific reservoirs are relevant.
HVAC Dust or Debris
Accessible air handlers, fan-coil units, registers and other HVAC deposits may be evaluated when the system is a suspected reservoir.
Prior Mold Remediation
Selected testing may be requested when questions remain about historical contamination, cleaning or residual dust after prior work.
Property Documentation
Owners, managers, attorneys and consultants may need documented findings for property, legal, insurance or facility records.
Post-Medical Consultation
Some clients request an environmental source assessment after discussing health concerns with a qualified medical professional.
Dust, surfaces, materials and building conditions
Environmental Mycotoxin and Mold-Related Testing Options
The final scope depends on the property, suspected source, sample matrix, laboratory requirements, access conditions and intended use of the findings.
Settled-Dust Mycotoxin Testing
Dust may be collected from selected horizontal surfaces or other reservoirs to evaluate certain mycotoxins in accumulated indoor dust.
Bulk Material Testing
Pieces of visibly moldy or water-damaged drywall, insulation, ceiling tile or other selected materials may be submitted for analysis.
Surface Sampling
Swabs, tape samples or other method-specific surface samples may be collected from suspect growth, deposits, contents or HVAC components.
Mold Source Assessment
Inspection, moisture measurements and building observations help identify areas where mold or damp materials may be present.
View mold inspection servicesMold Air Sampling
Air samples may be added when current airborne fungal conditions at selected indoor and outdoor locations are part of the investigation.
ERMI and HERTSMI-2 Sampling
DNA-based dust analysis may identify and quantify selected fungal species. It is a different test and answers a different question.
View mold dust testingHVAC Reservoir Assessment
Accessible fan coils, air handlers, filters, coils, drain pans, plenums and registers may be reviewed when HVAC dust is a concern.
View HVAC mold assessmentMoisture Assessment
Moisture meters, humidity readings, visual observations, leak history and thermal imaging when useful may help identify damp areas.
Written Environmental Report
Documentation may include observations, sample locations, laboratory findings, photographs, interpretation and limitations.
Different methods answer different questions
Mycotoxin Analysis Is Not the Same as Routine Mold Testing
A complete assessment may use one method or several complementary methods. The selection should be based on the actual question rather than ordering every available test.
Mycotoxin Analysis
Question: Are selected target compounds detectable in this sample?
- Dust, surface or material matrix
- Method-specific analyte panel
- Represents the selected sample only
- Does not identify the entire building extent
ERMI or HERTSMI-2
Question: Which selected fungal species are detected in collected dust?
- DNA-based fungal identification
- Usually collected from settled dust
- Influenced by dust age and cleaning
- Should not replace building inspection
Mold Air Sampling
Question: What airborne fungal spores are present at this place and time?
- Short-duration air collection
- Indoor and outdoor comparisons
- Influenced by activity and ventilation
- May not identify concealed growth
Surface or Bulk Mold Sample
Question: Is the selected growth or material fungal?
- Targets a specific suspect location
- Useful for visible or damaged materials
- Can identify fungal structures or groups
- Does not establish exposure or causation
Mold species and toxin production
The Presence of Mold Does Not Automatically Prove Mycotoxin Production
Some fungal species are capable of producing mycotoxins under certain environmental and growth conditions. Detecting a mold genus or species does not by itself establish that a toxin was produced in the sampled material.
Conversely, detecting a selected mycotoxin in one environmental sample does not determine the full source, distribution, route of exposure or medical significance. The finding must be evaluated with the sample matrix, location, building history and laboratory method.
Species capability
Some fungi can produce secondary metabolites under suitable
environmental conditions.
Actual production
Laboratory identification of mold does not automatically confirm
that a particular toxin was produced.
Environmental detection
A detected compound represents the selected sample and method.
Building interpretation
Moisture, material condition, dust reservoirs and source areas
remain central to the assessment.
Interpretation and limitations
What Environmental Mycotoxin Results Can Document
Results may document whether selected target compounds were detected in the collected dust, surface or material sample. They may also support a broader investigation of water-damaged materials, mold reservoirs or historical dust deposition.
Results should not be separated from the inspection findings. A laboratory number alone does not explain the moisture source, affected area, condition of concealed materials or whether the sampled dust represents current or historical deposition.
For a more detailed explanation, see what environmental mycotoxin dust and material results can—and cannot establish.
Results May Help
- Document selected sample findings
- Evaluate suspect dust or damaged materials
- Compare project-specific locations
- Support source-assessment decisions
- Organize findings for property records
- Identify questions requiring further inspection
Results Do Not Automatically Establish
- The condition of every room or concealed cavity
- The full extent of mold contamination
- A personal exposure dose
- The route or duration of exposure
- Medical diagnosis or causation
- The meaning of clinical laboratory findings

Frequently Asked Questions
What is environmental mycotoxin testing?
Environmental mycotoxin testing evaluates selected dust, surface or material samples for certain target compounds or mold-related indicators. It is not a medical test.
What types of samples can be tested?
Depending on the project and laboratory method, samples may include settled dust, surface material or pieces of visibly moldy and water-damaged building material.
Is mycotoxin testing the same as ERMI testing?
No. Mycotoxin analysis evaluates selected target compounds in a sample. ERMI is a DNA-based method that identifies and quantifies selected fungal species in collected dust.
Is mycotoxin testing the same as mold air testing?
No. Mold air sampling evaluates airborne fungal spores at selected places and times. Environmental mycotoxin testing typically evaluates selected dust, surface or material samples.
Does detecting mold prove that mycotoxins are present?
No. Some fungal species are capable of producing mycotoxins under certain environmental conditions, but identifying mold does not automatically prove that a particular toxin was produced.
Can one dust sample represent the entire property?
A dust sample represents the selected collection area and available dust at the time of sampling. It does not automatically represent every room, concealed cavity, material or HVAC condition.
Can environmental testing determine what caused my symptoms?
Environmental testing can document selected building conditions and laboratory findings. It does not diagnose illness, establish medical causation or replace evaluation by a qualified health care professional.
Do you test urine, blood or other medical samples?
No. Angstrom performs environmental inspection and sampling only. Medical testing and interpretation should be handled by qualified medical professionals.
Do you perform mold remediation?
No. Angstrom provides independent testing, assessment, sampling, consulting and reporting. We do not perform mold remediation, demolition, cleanup or reconstruction.
