Preanalytics

Excellence in preanalytics is critical for reliable laboratory diagnostics. Many factors before, during and after sample collection may affect the test results.

The information we have compiled for you on the following pages will help you understand the preanalytical factors that affect the sample material before testing. This will enable you to avoid “laboratory errors” and ensure the quality of the result.

You will find important notes on sample collection from different test materials, including blood, urine, stool, puncture and wound swab specimens.

Sample storage and shipment to the laboratory are further factors that play an important role in laboratory testing.

Furthermore, you will find general information regarding requests, as well as a list of the special codes ("Ausnahmekennziffern") that are relevant for medical practices.
