Preanalytiske
Preanalytiske, or the pre-analytical phase, encompasses all steps from test ordering and patient preparation to the moment a sample begins analysis in the laboratory. It covers patient identification, consent where relevant, collection procedures, labeling, the choice of specimen type and collection tubes, volume adequacy, and the initial handling, transport, and processing of specimens (such as centrifugation or aliquoting) before analytical measurement.
The goal is to preserve sample integrity and ensure that the specimen reflects the patient's condition at
Common preanalytical errors include mislabeling or specimen mix-ups, incorrect tube type or additives, insufficient volume, excessive
Quality assurance in the preanalytical phase relies on standardized procedures, training and competency assessment, specimen handling
Improving preanalytical processes reduces rework, lowers costs, and shortens turnaround times, while enhancing the reliability of
