A useful laboratory request begins with the investigation question.
PBR Laboratories’ air-testing services include bacterial enumeration, mould testing, combined yeast-and-mould enumeration and selected E. coli and coliform tests. Consultants can discuss method suitability and sample acceptance before arranging collection. PBR serves projects across Canada, prioritizing Alberta and Western Canada; confirm sample transport and, where applicable, rental collection or delivery arrangements for your project.
Specify whether the investigation concerns a microbial count, a selected target or a comparison between collected samples. Provide the collection method, locations, relevant observations and intended use of the report. Avoid broad requests for complete air-quality certification.
If deciding between count-based or target-based testing, read Air Enumeration versus Presence/Absence Testing.
The laboratory analysis describes the submitted sample using the selected method. The responsible consultant should establish the sampling design, comparison approach and wider conclusions. Confirm any PBR field-service involvement separately; sampler rental alone does not establish on-site collection.
If sampling equipment is required for your project team, review our Air Sampler Rental for Canadian Testing Projects.
For residential building concerns, Health Canada does not recommend routine mould air testing. Moisture and inspection findings remain fundamental to assessing indoor building environments.
If laboratory sampling has a defined project purpose, ensure the method and result can answer that question. Do not treat a laboratory number as a health-risk assessment or blanket clearance. Learn more on our Mould Air Testing page.
Following an unexpected result, review the collection record and project objective before deciding what additional evidence is needed. Further analysis or sampling may be appropriate, but repeating an analysis alone does not establish the source or resolution of a concern.
For a structured review protocol, see What to Do After an Unexpected Air Microbiology Result.
Provide the project type, organisms or count of interest, collection equipment or medium, sample locations, sample number, intended comparison criteria and delivery schedule. Ask PBR to confirm accepted samples and reporting requirements.
For sample packaging and chain-of-custody guidelines, consult Planning Air Microbiology Sample Collection and Submission.
Not by itself. A wider conclusion requires the project’s investigation, sampling design and applicable professional assessment.
Contact PBR with the proposed collection method and requested analysis before collecting samples.
No. Collection method, recovery approach and reporting units can differ. Compare like-for-like data only when the methods and context support that comparison.
Discuss analytical methods, sampler rental, and submission logistics with PBR Laboratories for your consulting and environmental projects.
