1 – Program overview

Haemolysis, icterus and lipaemia of biological samples are the source of analytical interference. Most analysers currently offer a possibility of quantifying serum indices allowing automated management of this interference. However, there is no standardisation of these measures.

The aim of the proposed program is to help the laboratory better control the quality of serum index measurements by enabling it to assess their accuracy.

This program is suitable for all analysers performing a measurement of serum indices (chemistry analysers, haemostasis, serology, etc.).

INFORMATION: Two posters were presented during the 1st Francophone Days of Medical Biology, in September 2017, in Bordeaux:

• "EQA on haemolysis interference: results of a pilot survey" ==> Download the PDF (in french)
