Remarks The primary aim of the Clinical Microbiology Laboratory proficiency testing scheme (CLS) is to enable laboratories performing the microbiological analysis of clinical samples to monitor their performance and compare it with that of their peers. The CLS scheme also aims to provide information to participants on technical issues and methodologies relating to Clinical Microbiology. The CLS scheme year operates from January to December. Further information about CLS, including test material availability, round despatch dates and reporting deadlines, are available on the current CLS application form. The operation of the scheme is supported by an Advisory Group consisting of experts in the field of Clinical Microbiology. The scheme is run in collaboration with the American Proficiency Institute (API). The scheme reports on the performance of U.K. participants to the National Quality Assurance Advisory Panel for Medical Microbiology.
