EQA RESIDUAL LEUKO
Program description:
"EQA RESIDUAL LEUKO" is an external quality assessment program that controls the quantification of residual leukocytes (rWBC) in globular and platelet concentrates on flow cytometry, Nageotte’s counting chamber, and automated cells counter ADAM-rWBC.
Shipments are scheduled twice a year (May and August) with four samples : 2 tubes with 1ml of platelet concentrate and 2 tubes with 1ml of globular concentrate.
Parameters:
Number of WBC per microliter or 106/L : rWBC
Comparison groups:
All techniques comparison: Statistical treatment made with all the EQA results, all techniques included.
Peer group comparison: Statistical treatment made with the EQA results from laboratories which use the same manufacturer’analyzers.
We identified 3 peer groups for this program:
Flow cytometry
Adam-rWBC
Nageotte’s counting chamber
(Residual leukocytes detection)
