I was asked about this last week. Here is a simple guide for what devices to use when taking source samples for microbial investigation.

I. Surface
A. Tape (for dry and even surface): non-culturable, non- quantitative results
- Dry wall, wood surface, etc.
- Ceiling tile (if most of visible biomass are on the top)

B. Swab (for wet or uneven surface): quantitative results
- Dry wall, wood surface, etc.
- Ceiling tile (if most of visible biomass are on the top)

II. Subsurface (and/or Surface)
A. Bulk
- Air filter: If significant amount of dust is accumulated on the filter, use micro-vac first and then cut a bulk piece. Pull filter off metal supporting mesh first before cutting.
- Ceiling tile: Cut a bulk piece if most of the biomass is inside of the material and cannot be removed by swabbing.
- Decayed wood, etc.

B. Micro-vac (for loose biomass)
- Carpet dust, floor dust, etc.

We have been helping companies that were frustrated with unsatisfying services from their microbiology labs on issues such as:
(1) poor technical support
(2) no personal attention
(3) questionable results
(4) project delay; slow turnaround time
(5) reports not making sense
(6) lack of ethics
