Lab-Certified Mold Testing
for Preston, MN Properties

Spore trap (non-viable) testing collects all airborne particles and identifies them by genus under microscopy — results in 24–48 hours, genus-level data. Viable culture plates capture only live, culturable spores and grow them on culture media for species-level identification — results in 5–7 business days. For most routine Preston, MN air quality screening, spore trap sampling provides sufficient data faster. Viable culture is used when species-level confirmation matters — Stachybotrys investigation, occupational health documentation, or situations where genus data doesn't answer the specific question at hand.

Consumer kits detect presence, not concentration — and they grow positive in nearly every environment. For any situation where results need to support a decision (insurance claim, real estate transaction, remediation planning), accredited lab analysis via calibrated air sampling is the required standard in Preston, MN.

Minimum two indoor plus one outdoor comparative. Additional samples per floor, zone, or HVAC register depending on the scope of the question. We tell you specifically how many are warranted for your Preston property before booking.
