Mold & Bacteria Consulting Laboratories (MBL) Inc. provides laboratory mould testing and identification. We also provide testing for environmental bacteria. Mould testing services include analysis of non-viable air samples (Air-O-Cell, Micro 5, cyclex D, LARO-100, pcm cassettes), viable air samples (RCS, Andersen, etc), direct microscopic and culture analyses of bulk samples (drywall, wallpaper, pieces of carpets, insulation material, dust, wood and other matrices), lift tape and swab or wipe samples. We also assist industrial and occupational hygienists, certified mould inspectors, environmental engineers and other consultants in troubleshooting mould and bacteria problems in industrial, hospitals, offices and residential buildings.
Turnaround time for all culture analyses is 10-14 days. Non-culture analyses takes 2-5 days for regular service and 24 hours for rush service. Please call if you need sampling information or a list of our prices. Download our Chain of Custody (Analysis Request Form.

Mould Testing:
- Air Samples
Culture (viable) analysis. This includes enumeration of the colony forming units (CFU) and identification of moulds to genus or species. Samples may include RCS, Andersen, LARO-100, or any other media suitable for culture analysis. The report includes a list of recovered moulds and their concentration as colony forming units (CFU), a statistical comparisons of samples where possible and information on the recovered moulds where available. - Non-viable (total spore count) Analysis. Samples include Air-O-Cell, VersaTrap Cassette, VersaTrap Sampling Cassettes, SKC BioStage, SKC BioCassette, Micro 5, Cyclex D, LARO-100, PCM and other cassettes. This analysis involve spore counting and identification of different categories of mould spores. The report includes spore counts for each category of spores and the grand total spore count for all spores per cubic meter of air. Wherever possible spore counts and categories of spores for all the samples are compared.
- Bulk samples (e.g., drywall material, wallpaper, pieces of carpet, etc). Bulk samples could be analysed by either DME or culturing. A report for DME analysis gives a listing of the observed moulds in rank order. Information of the recovered moulds is also given. Culturing involve identification of recovered moulds to species and listing them in rank order.
- Surface swabs. Swabs could be analysed by direct microscopic examination (DME) or culturing. A DME report for these samples is similar to that of bulk samples. A culture report includes a list of the recovered moulds identified to species level and concentration of these moulds if the analysis involved quantification.
- Lift Tape samples. Tape samples are usually analysed by DME but could also be analysed by culturing. The report produced here is similar to that of DME for bulk samples.
- Dusts (from carpet, upholstery, mattress etc.), Soils and other sediments. These samples are suitable for either culturing without quantification (Direct Plating) or with quantification. They may also be analysed by DME. A report for culturing for quantification lists the recovered moulds and their concentration as CFU per gram of dust or per unit area.
- Sewage and sludge. Suitable for analyses by culturing. Could also be analysed by DME. Reports produced for these samples are similar to those of other samples.
Bacteria Analyses:
The samples discussed above except for lift tape and non-viable air samples could all be analysed for culturable bacteria. Since virtually every sample has some form of bacteria, it is important to have a clear objective for bacteria analysis. Also, some samples are not suitable for bacteria analysis or for some categories of bacteria. MBL analyses samples for the following bacteria:
- Gram Staining and Enumeration of Culturable Bacteria
- Total Coliform / E. coli (Presence/Absence)
- Total Coliform / E. coli (MPN)
- Total Coliform (membrane filter)
- Fecal Coliform (membrane filter)
- Standard Heterotrophic Plate Count
- Legionella Detection.
Consulting Services
We are happy to offer assistance to industrial and occupational hygienists, certified mould inspectors, environmental engineers and other consultants in designing sampling strategies and also determining the most suitable types of samples to take for a given investigation. We also assist field consultants in troubleshooting mould and bacteria problems in industrial, hospitals, offices and residential buildings.
