Laboratorieutvärdering

Laboratorieutvärdering, or laboratory evaluation, refers to the systematic assessment of laboratory procedures, equipment, and data to ensure accuracy, reliability, and compliance with regulatory standards. The process typically involves both internal and external evaluation components. Internal evaluation includes proficiency testing, method validation, performance statistics, and quality control procedures, while external evaluation may involve accreditation reviews by organizations such as ISO, CLIA, or national quality authority bodies.

Key steps in laboratorieutvärdering include defining evaluation objectives, selecting appropriate evaluation criteria, collecting performance data, analyzing results, and implementing corrective actions. Common evaluation metrics are accuracy, precision, sensitivity, specificity, turnaround time, and sample integrity. Validation studies verify that analytical methods meet predefined performance requirements before they are applied to patient samples.

Laboratorieutvärdering is critical in clinical laboratories to support accurate diagnostics, patient safety, and health system quality. Medical laboratories routinely use external proficiency testing programs to benchmark their performance against peer labs. In industrial and environmental contexts, laboratory evaluation assures compliance with safety and environmental regulations. The continuous cycle of assessment, feedback, and improvement aligns laboratories with best practices and evolving scientific standards.
