From basic air quality screening to forensic-level fungal investigation — the right test for your situation.

Non-Viable Spore Trap Air Sampling
The workhorse of mold air testing. Spore traps collect non-viable particles — both live and dead spores — giving total spore counts by genus. Standard for most Knoxville residential and commercial testing scenarios.
🏭
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 Knoxville, MD use case.

Surface Swab & Tape Lift Sampling
Surface sampling from visible staining in your Knoxville property confirms whether it's mold (not just discoloration) and which species — important for remediation protocol decisions.
📄
Post-Remediation Clearance Testing
After mold remediation, clearance testing compares treated zone air samples to outdoor baseline — confirming indoor spore counts are back to acceptable levels before re-occupancy. Our Knoxville, MD clearance testing uses the same accredited lab protocol as pre-remediation sampling, so results are directly comparable.
🏢
HVAC & Ductwork Air Testing
Register-versus-room comparative sampling identifies whether your Knoxville, MD HVAC system is amplifying or distributing mold — essential before deciding whether duct cleaning will actually help.
🔋
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 Knoxville, MD property. ERMI uses qPCR analysis on settled dust to identify 36 mold species — often used in post-remediation verification or occupant health investigations.
