Emma, I will be forwarding this to my Haematology colleagues to ask if they can help. But please may I make an appeal (oft repeated). It is NOT external quality control. It's external quality assessment (EQA). It may seem to be a pedantic point, but there is a difference between control and assessment of quality, even though the 2 functions are closely interrelated. Best wishes, Chris Royle, Laboratory Manager (Clinical Biochemistry and Haematology Departments), Royal Brompton Hospital, Sydney Street, LONDON SW3 6NP Tel.

I am also trying to find a source of external quality control material for these devices if anyone knows of one.
