From basic air quality screening to forensic-level fungal investigation — the right test for your situation.
💨
Non-Viable Spore Trap Air Sampling
Spore trap cassettes collect airborne particles that are then analyzed under microscopy to identify mold genera and count spore concentrations. Compared against an outdoor baseline sample, this data shows whether indoor spore counts are elevated and which genera are present. Fastest turnaround for routine Winthrop, MN air quality assessment.
🏭
Viable Culture Air Sampling
Culture plates capture live, culturable mold spores that then grow in the lab — allowing species-level identification and colony-forming unit counts. Used when species-level data matters: occupational health concerns, Stachybotrys investigation, or situations where genus-level data from spore traps isn't sufficient for your Winthrop, MN use case.
🎖
Surface Swab & Tape Lift Sampling
Surface sampling from visible staining in your Winthrop property confirms whether it's mold (not just discoloration) and which species — important for remediation protocol decisions.
📄
Post-Remediation Clearance Testing
Independent clearance testing after any Winthrop, MN remediation job — whether we did the work or another contractor did. Lab report confirms the job is objectively complete.
🏢
HVAC & Ductwork Air Testing
Testing at HVAC registers and returns identifies whether the air distribution system is a mold source. High spore counts at registers compared to room-level samples indicate the system is contributing to indoor air quality problems — a critical finding before any duct cleaning or coil remediation decision in Winthrop.
🔋
Bulk & ERMI Sampling
Bulk material samples and ERMI (Environmental Relative Moldiness Index) floor dust sampling give a cumulative picture of historical mold presence in a Winthrop, MN property. ERMI uses qPCR analysis on settled dust to identify 36 mold species — often used in post-remediation verification or occupant health investigations.
