glucose tubes contain sodium fluoride as a glycolysis inhibitor. The anticoagulants K3EDTA, potassium oxalate or sodium heparin prevent the blood from clotting. The citrate/citric acid buffer reduces the pH value in the sample immediately after blood collection leading to an instant stabilization of glucose. Depending on the test system, VACUETTE®
glucose tubes can also be used for lactate assays, with in most cases sodium fluoride being used in combination with potassium oxalate.
Our gray top glucose blood tubes are used to preserve glucose in whole blood. See our available Sodium Fluoride tubes here in a variety of sizes and types.
