Quality assurance in microbiology.
Quality assurance (QA) is the total process whereby the quality of laboratory reports can be guaranteed. The term quality control covers that part of QA, which primarily concerns the control of errors in the performance of tests and verification of test results. All materials, equipment and procedures must be adequately controlled. Culture media must be tested for sterility and performance. Each laboratory must have standard operating procedures (SOPs). QA of pre-analytical, analytical and post-analytical stages of microbiological procedures should be incorporated in SOPs. The laboratory must be well lit with dust-free air-conditioned environment. Environmental conditions should be monitored. Supervisory and technical personnel should be well qualified. The laboratory should participate in external and internal quality assurance schemes.
