Laboratory medicine: Confirming diagnoses and supporting treatments – quickly, efficiently and correctly.

Extra-Analytical Quality

Quality requirements outside the laboratory

The section „Extra-analytical Quality Assurance“ was formed on the basis of the former WG „Pre-analytics“. The focus of this WG is on central aspects of pre- and post-analysis. The following goals are currently being pursued:

  • The compendium „The Quality of Diagnostic Samples“), already written by the WG „Pre-analytics“ in cooperation with BD, is continuously updated and converted into new media forms (e.g. a mobile app, which DGKL members can already download free of charge in the member area).
  • The establishment of a standard catalogue for stability testing
  • The development of an interlaboratory survey for pre-analytics
  • Standards-based training presentations for physicians, MTA, BMA and nurses
  • Harmonizing the color coding of blood collection tubes


In 2017, the section published a standard working manual for peripheral venous blood sampling for laboratory medical diagnostics at De Gruyter Verlag. The Pdf is available here.
