Many microbial contaminants do not present obvious signs.
They often lurk on or within surfaces: walls, flooring, HVAC components, baseboards, ductwork, or other hard-to-inspect areas following water intrusion. Visual inspection alone cannot reliably reveal these hazards.
Swab sampling is a proven method used by inspectors and others to detect microbial contamination (mold, bacteria, etc.) or other surface-borne hazards. It is widely used in environmental monitoring, remediation verification, and hygiene verification across multiple industries.
By offering a Category Determination Swab test through PriorityLab, you empower your clients with a definitive answer: “Is this surface contaminated, or not?”
Why choose PriorityLab for Category Determination Swab Testing
- Reliable surface sampling protocols, Use sterile swabs and validated lab methods to collect samples from smooth and porous surfaces, especially in moisture-prone or previously water-damaged areas.
- Accurate microbial detection, Identifies presence of mold, bacteria, or fungi on surfaces, including species-level or colony count analysis where needed, giving you defensible, professional-grade results, built on the IICRC S500 Standard.
- Versatility, works on uneven or difficult surfaces, Because swab testing doesn’t require large sampling areas or visible growth, it’s ideal for tight spots, baseboards, behind cabinetry, HVAC surfaces, window frames, and more.
How to sell it to your clients
- Pre-renovation safety assessment, Before renovations begin show proof of category to insurance adjusters
- “Hidden-hazard verification” for buyers, sellers, landlords, and homeowners, Especially valuable in homes with moisture damage or previous mold problems.
