Studies show that preanalytical errors are the reason for 62% of all errors in laboratory medicine [1]. “The diagnostic consequences depend on the magnitude of the preanalytical error. In worst case, these errors may lead to mistreatment of patients; in all cases, these errors are an extra workload for the hospital staff involved” [2].

A key feature in this app, the handbook section contains videos showing how to properly collect a blood gas sample by arterial puncture, through an arterial line or by capillary sampling. It also describes several types of errors that can occur during and after sampling and gives tips on how to avoid such preanalytical errors.

The recommendations provided by the app are based on existing literature and international best practices.


Exceptionally high or low values of a given parameter may be due to one or several types of preanalytical errors. The troubleshooting section is a good tool when you are experiencing difficulties evaluating if measured results reflect patient status or if a preanalytical error may have occurred.
