Description
Laboratory supplies » Blood collection and sampling » Venous blood sampling » Glucose and lactate analysis
Glucose tubes are available in Sodium Fluoride w/ Potassium Oxalate or Sodium Fluoride w/ Sodium EDTA additive combinations. Glucose values in unpreserved blood samples decrease quickly after collection as glucose is metabolised by the blood cells. The Fluoride additive stops the enzymatic activity of the glycolytic pathway. One advantage of the Fluoride w/ EDTA tube over the Fluoride w/ Oxalate tube is that the marker HbA1c can be determined from the same tube, so no additional tube sample needs to be taken.
