Stable lyophilized ethylenediaminetetra-acetic acid (EDTA)-blood haemolysates were applied in an external quality assurance programme (SKZL, The Netherlands) for glycohaemoglobin assays in 101 laboratories using 12 methods. The mean intralaboratory day-to-day coefficient of variation (CV), calculated from the assay of 12 unidentified pairs over a period of 1 year, was 5.2% (range: 0.2-28.7). Forty-seven per cent of laboratories did not meet the criterion of CV < 5%, whereas 68% did not meet the… CONTINUE READING
