CRITERIA FOR QUALITY LABORATORY PERFORMANCEIf these systems are used to report presumptive identification of organisms, the key components, uponwhich the laboratory’s level of identification is based, needs to be validated to give appropriate reactions inthe presence of known organisms.In some cases it may not be feasible to maintain a complete cadre of organisms to be able to establish bothpositive and negative reactivity for every potential component used by the system to make identification.The laboratory must challenge the system with the organisms suggested by the manufacturer, commonlyavailable, easily maintained, and that represent those organisms most commonly identified among the laboratory’spatient population.M 10 RDoes the microbiology record, for each sample, include documentation of the reactivity noted for each step ofthe identification process?This documentation will vary based on the identification system in use. It should enable staff to look backand verify that the identification reported based on the reactions observed is valid. Common items to includein documentation are: growth characteristics on various media, positive or negative reactivity with variousstain, reagents, or disks. This documentation provides valuable information if there is a question later aboutthe interpretation of results that lead to identification of a specific organism on the final report.42. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .FOR MORE INFORMATION CONTACT COLA PHONE 800.981.9883 | FAX 410.381.8611 | ON-LINE www.cola.org
