Objectives: To evaluate changes in plasma glucose measurements in an unselected patient population after a change of recommendation from NaF to citrate blood collection vacuum tubes. Design and methods: Glucose (n = 460 751) and HbA1c (n = 55 190) determinations during a period of approximately three years before and after the tube change were extracted from a laboratory information system. Results: Median values for plasma glucose determinations increased from 6.03 before to 6.28 mmol/L after the tube change. The proportion of glucose determinations above the WHO limit for impaired fasting glucose (6.1 mmol/L) and the medical decision limit for diabetes (7.0 mmol/L) increased from 48.1 to 55.4% after the change. Conclusions: The change from NaF to citrate tubes caused higher glucose values, and consequently more glucose determinations above the decision limit for diabetes.
