The effect of target values on the performance of photometric glucose results in a general clinical chemistry EQA-scheme
Labquality, a Finnish independent EQA provider, organizes a general clinical chemistry
program six times a year. In this scheme, the clients can respond up to 50 analytes
and they fill in their method and device information together with their results. In this
scheme, transferred values from NFKK Reference Serum X are used as target value for 16 components. For the remainder of the components the assigned values are consensus
values calculated according to ISO 13528 algorithm A. Sometimes also samples with
reference method values are used.
