Testing without Full Inspection
Targeted mold testing when you specifically need lab data.
Mold testing is appropriate when you don't need a full inspection, you need specific lab data. Common scenarios: prior inspection findings need quantification, healthcare provider has identified a specific question, or insurance documentation needs an objective measurement.
3 Laboratory Samples Included Add-on samples available
What is mold testing?
Mold testing is laboratory analysis of air, surface, or dust samples collected from a building, to identify the mold genera or species present and the concentrations in indoor air. Standard methods include calibrated spore-trap air sampling always paired with an outdoor reference, surface tape-lift or swab sampling on visible growth, and dust DNA panels such as ERMI and HERTSMI-2 for water-damaged-building markers. Each method answers a different question. Air describes conditions at the moment of sampling, a surface sample confirms what a specific patch actually is, and settled dust describes what has accumulated over time. That is why the right test depends on the question being asked, and why a sample taken without an inspection behind it often produces a number with no explanation attached. Results come from an AIHA-LAP-accredited third-party laboratory and are interpreted in a written report.
What it covers
What's included?
- Air sampling. Calibrated spore-trap collection (Air-O-Cell or equivalent), indoor with an outdoor reference, to quantify what is airborne.
- Surface sampling. Swab or tape-lift of visible growth for species-level identification.
- Wall-cavity sampling. A minimally invasive check for hidden growth inside a wall where history or moisture readings point to it.
- Lab analysis with species ID. Samples ship under chain of custody to an AIHA-LAP accredited third-party laboratory and are interpreted, not just reported.
- Stakeholder-ready documentation. Results formatted for the healthcare provider, insurer, or other party that requested the data.
Optional lab testing
Testing you can add.
Three laboratory samples, air, surface, or wall-cavity, are included. When you need dust-based or chemical data instead of a spore count, any of these specialty panels can be added, and the cost is quoted up front:
- ERMI & HERTSMI-2 dust panels. DNA-based mold analysis scored against water-damaged-building markers, frequently requested for CIRS and MCAS medical documentation.
- Mycotoxin testing. Detects the toxins some molds produce, a different question than how many spores are present.
- Pathways™ testing. Microfiber-swab sampling analyzed for peptide-bond protein, collected to manufacturer protocol.
- VOC & formaldehyde testing. Chemical off-gassing measurements for indoor-air-quality concerns beyond mold.
- Endotoxin testing. Bacterial-marker analysis for water-damaged or agricultural environments.
- Legionella water testing. Sampling of building water systems, cooling towers, potable water, spas, and fountains, for the bacteria that causes Legionnaires’ disease.
Add-on panels: ERMI, HERTSMI-2, mycotoxin, Pathways™, VOC, formaldehyde, endotoxin, and Legionella water testing. Every sample ships under chain of custody to an accredited third-party laboratory.
Air sampling
When is air sampling useful, and when is it not?
Air sampling draws a measured volume of air through a spore trap, and the laboratory counts and identifies what it caught. Indoor results only mean something against an outdoor sample taken the same day, because Florida outdoor air carries plenty of spores by default, often more than the indoor air does.
It is useful when:
- Someone is reacting indoors and you need a number rather than an opinion
- Visible growth has been remediated and you need clearance data against an outdoor baseline
- An insurer, landlord or physician has asked for an objective measurement
- You need to compare one room against another to narrow down where a problem sits
It is a poor choice when it is the only thing you do. An air sample describes one moment in one room. Mold does not release spores continuously, so growth inside a wall cavity, under flooring or behind an air handler can be actively present while the air reads unremarkable. Running the HVAC, recent cleaning, closed windows, or simply sampling on a quiet day all move the number. That is why a normal air test does not rule out hidden mold, and why I read the building, its moisture and its HVAC before deciding whether an air sample is even the right instrument.
If the question is is there mold in this building and where, the building answers it and sampling confirms it. If the question is how much is airborne right now, air sampling is exactly the right tool. Matching the test to the question is most of the value.
When you need it
When is this service the right fit?
- Healthcare provider has requested specific data
- Insurance carrier needs quantified measurement
- Post-cleaning verification (informal)
- Spot-check after a partial remediation
- Comparison testing across multiple rooms or units
How this service works
How does mold testing actually work?
Three methods, each answering a different question. The method is chosen from the question you came with.
01Decide what is being asked
Air describes conditions at the moment of sampling. A surface sample identifies what is on a specific spot. Dust describes accumulated history. They are not interchangeable.
02Air sampling
Calibrated spore-trap sampling, always paired with an outdoor reference taken the same day. Without the outdoor pair an indoor count means very little.
03Surface sampling
Tape-lift or swab taken directly on visible growth, to identify what is actually there.
04Dust panels
ERMI and HERTSMI-2 DNA panels for water-damaged-building markers, where accumulated history is the question.
05Accredited laboratory, then report
Samples travel under chain of custody to an AIHA-LAP-accredited third-party laboratory, and the report states genera or species and concentrations.

Honest answers
Mold testing, answered.
Which mold test should I ask for?
It depends on the question. Air sampling describes conditions at the moment of sampling, a surface sample confirms what a specific patch actually is, and settled-dust DNA panels describe what has accumulated over time.
Do you always take an outdoor reference sample?
For air sampling, yes. An indoor spore count means very little without the outdoor baseline taken the same day, because outdoor conditions set the frame the indoor number is read against.
What lab analyzes the samples?
An AIHA-LAP accredited third-party laboratory, with chain of custody on every sample. PureSpec does not run its own lab, and the results are interpreted in a written report rather than handed over as raw numbers.
Is mold air testing the same as a mold inspection?
No, and the difference matters. Mold air testing measures what is airborne at the moment the sample is taken, compared against an outdoor reference. It is one instrument reading, not an assessment. A proper mold inspection reads the building first: moisture, the HVAC system, the envelope, and where water has actually travelled, then samples where the findings call for it. An air test on its own can come back unremarkable while growth sits inside a wall cavity, which is why I do not sell air testing as a substitute for looking at the building.
