Glucose and lactate determination BD Vacutainer® glucose tubes are available in Sodium Fluoride, Potassium Oxalate and Sodium Fluoride EDTA. Glucose values in unpreserved blood samples decrease quickly after collection as glucose is metabolised by the blood cells. The additives contained in BD Vacutainer® Fluoride/Oxalate and Fluoride/EDTA tubes will stop enzymatic activity at the glycolytic pathway. HbA1c determination One advantage of the Fluoride/EDTA tube over the Fluoride Oxalate tube is that the marker HbA1c can be determined from the same tube, so no additional tube sample needs to be taken.
