Finding growth, measuring a count and identifying an organism are different laboratory questions. Choose the requested work according to what you need to learn from the submitted sample.
Growth assessment records findings under the agreed examination and incubation conditions. The meaning of the finding depends on the sample, medium and method. A report of no observed growth applies to those conditions and is not proof that every organism is absent.
Enumeration provides a count under a defined procedure and reporting basis. Confirm the units and sample basis before comparing results. Counts from different media, collection approaches or conditions may not answer the same question.
Identification seeks to characterize recovered growth to the level supported by the applicable approach. A count does not provide an identification by itself. Discuss the required identification detail before work begins; the same level of resolution may not be achievable for every isolate.
Review the sample identity, collection history, method, reporting units and any qualifiers alongside the intended specification or monitoring objective. An identification alone does not establish a contamination source. A single result does not describe every location, time or unit in a larger system.
For an unusual finding, contact PBR promptly with the report reference and investigation question. Discuss whether retained growth is available and whether identification or another defined analysis would add useful information. Follow-up testing should support the investigation rather than automatically repeat the original request.
Discuss identification of recovered bacteria, yeasts and moulds and the detail your investigation requires.
Arrange incubation and growth assessment of client-submitted monitoring plates, with identification where required.
Discuss microbial activity in industrial and environmental samples within a defined investigation.
Review the information and arrangements to confirm with the laboratory before collecting plates.
Distinguish product evaluation objectives before selecting a laboratory test.
Connect routine facility monitoring and investigation needs with the appropriate laboratory service.
Plan laboratory work around environmental project objectives and sample context.
Contact PBR with your sample or product, testing objective and reporting needs. Confirm the appropriate laboratory scope and submission arrangements before sending material.
