1 – Program overview

The NUM EQA program is designed for the quantitative assessment of CBC analytes with peer-group between-laboratory comparisons and trend monitoring for automated instruments.

Two optional programs are associated with this program :

• EQA - NFR : CBC and reticulocytes in fresh blood
• EQA - RETI : Reticulocytes (stabilized blood)

Participating labs can choose to be assessed for all the analytes of this program, or simply a subset of analytes of interest.
