The results of HbA1c measurement and its comparison with reference method values in an EQA programme
Publikováno v:
Accreditation and Quality Assurance. 15:239-243
This article describes the effect of a change in reference method for HbA1c measurement on results in our EQA programme. Important indicators of analytical quality, particularly reproducibility, bias and uncertainty, were assessed. Basic analytical q
