Laboratory personnel were asked to register rejections, and causes for rejection of ward as well as out-patient samples collected in the laboratory. Plebani and Carraro observed in their paper that the great majority of errors result from problems in the preanalytical or post-analytical phases.3. How can we make laboratory testing safer?

Nurses' experiences of blood sample collection from children: a qualitative study from Swedish paediatric hospital care. Errors arising during sample processing are classified into preanalytical, analytical, and post-analytical, depending upon their source and time of presentation respectively. The increasing rate of preanalytical errors in this study and more specifically in OPD and IPD suggests the need to review the existing preanalytical procedures and explore if procedures should be changed to reduce the risk of errors. Laposata, M. and Dighe, A. Currently, pre-analytical errors account for up to 70% of all mistakes made in laboratory diagnostics, most of which arise from problems in patient preparation, sample collection, transportation, and preparation for analysis and storage.
