Understanding Your Test Results
Your report is written in plain language, but a little context helps. Here's how to read your results, what the categories mean, and how to decide what to do next.

What's in your report
Every Home Test Pros report includes a summary of findings, the lab-verified data behind them, and clear recommendations. You don't need a science background to use it — the summary tells you what we found and what, if anything, to do.
- Summary & risk level — the headline result for each area tested.
- Detailed lab data — spore counts, particle levels, or moisture readings.
- Recommendations — practical, prioritized next steps.
- Methods — how samples were collected and analyzed.
Result categories explained
To keep things clear, results are grouped into simple levels. The exact thresholds depend on the test type and lab, but the idea is consistent:
LOW Within normal range
Indoor levels are comparable to or below the outdoor baseline, with no unusual indoor-only findings. No action typically needed beyond normal home upkeep.
MODERATE Worth a closer look
Levels are somewhat above baseline or a minor concern was detected. Often resolved with better ventilation, humidity control, or addressing a small moisture source.
ELEVATED Recommend action
Indoor levels are notably higher than outdoors, or water-damage-associated species or pollutants are present indoors. The report identifies likely sources and recommended next steps.
The outdoor baseline
Mold spores exist everywhere outdoors, so a raw indoor number means little on its own. That's why we take an outdoor control sample the same day. Comparing indoor to outdoor is the most meaningful way to tell whether your home has its own mold source rather than just reflecting the neighborhood's air.
Key idea: it's the comparison between indoor and outdoor — and which species appear — that matters, not a single scary-looking number.
Common terms
- Spore count — estimated mold spores per cubic meter of air.
- Genus / species — the type of mold identified; some are associated with water damage.
- VOCs — volatile organic compounds; gases from products and materials.
- Particulates (PM2.5/PM10) — fine airborne particles affecting air quality.
- Relative humidity — moisture in the air; sustained high humidity encourages mold.
- Moisture content — how wet a material is; high readings suggest a leak or intrusion.
What to do next
- Read the summary first — it tells you the overall picture quickly.
- Note anything marked moderate or elevated and the recommended action.
- If a moisture source is identified, addressing it is usually the priority.

- Had remediation done? Consider post-remediation verification to confirm the issue is resolved.
Results FAQs
What is a normal mold spore count?
There is no single universal 'safe' number. Labs compare your indoor sample to an outdoor baseline taken the same day. Indoor levels that are similar to or lower than outdoors, with no unusual indoor-only species, generally indicate no active indoor mold source.
My report says 'elevated' — does that mean my home is dangerous?
Not necessarily. 'Elevated' means indoor levels are higher than the outdoor baseline or that water-damage-associated species appear indoors. It's a signal to investigate the source, not an automatic emergency. Your report explains what was found and recommended next steps.
What are VOCs on my air quality report?
VOCs (volatile organic compounds) are gases released from products like paints, cleaners, new furnishings, and building materials. Some are harmless at low levels; the report flags concentrations worth addressing through ventilation or source removal.
How soon should I act on my results?
If the report identifies an active moisture source or elevated indoor mold, addressing it sooner limits further growth and damage. Your report prioritizes findings so you know what's urgent and what's routine.
