Collecting dust from the wrong places can distort lab results. To ensure your sample reflects the true mold DNA load in the air and surfaces you live around, avoid the following locations:

Avoid Sampling:

• Bathrooms, Kitchens, Laundry RoomsThese spaces have naturally elevated humidity and other contaminants like soap, food particles, and detergent residue that may skew the results.
• Visible Mold SourcesDon’t swipe directly over visible mold. These high concentrations can overwhelm the test and prevent you from seeing your home’s typical background levels.
• Floors and BaseboardsWhile tempting, floor dust contains heavier debris and unrelated particles that distort DNA testing. Focus on above-floor surfaces.
• Areas Near Windows, Doors, and Vents to OutsideThese areas may contain outdoor contaminants that don’t reflect your home’s indoor air quality.
• Rusty or Recently Disturbed SurfacesRust particles or freshly cleaned surfaces may interfere with analysis or give a false negative.
• Near Heat SourcesStoves, heaters, and radiators can alter or degrade dust particles, making them unreliable for DNA testing.
• Post-Construction AreasAvoid collecting from any area recently remodeled, especially where drywall dust is present. Construction dust is not representative of settled biological particulates.

✅ Summary Tip:

Sampling for MSqPCR is not about finding visible mold—it’s about detecting what’s suspended and resettled in your breathing space. By collecting from high, undisturbed, everyday surfaces, your test results will give you a more accurate picture of your indoor environment.
