Labquality Days - Nordic Congress on Quality in Laboratory Medicine


The awareness of the importance of preanalytical factors increases exponentially these years as illustrated by this meeting. Many of these factors are difficult to control, among which patient preparation and blood sampling without doubt is crucial for a correct analysis result. However, information about patient preparation often takes place outside the “jurisdiction” of the laboratory, and blood sampling is also often performed by persons outside the laboratory, so these processes seems difficult to control by the laboratory. But the more difficult it seems, the more important it is that the laboratory plays an active role in information regarding these aspects: Knowledge on what influence erroneous patient preparation has on the analysis results and how correct blood sampling is vital for a reliable analysis result is sparse outside the laboratory; an important task is therefore to inform on these issues and to offer tools for quality assessment and quality control outside the lab.


This talk will briefly introduce these two preanalytical aspects, give examples on what erroneous patient preparation and blood sampling can result in, and finally present suggestions to how these important parts of the laboratory process can be included in the quality control system.
