WebThese include red-top collection tubes with serum separator, grey-top tubes with a fluoride glycolysis inhibitor, and heparin-containing green-top tubes which prevent clot formation. WebWhy sodium fluoride is used as anticoagulant? Sodium Fluoride Mechanism of action: It acts in two ways: As an anticoagulant by binding the calcium. As an enzyme inhibitor that prevents the glycolytic enzyme from destroying the glucose. Sodium fluoride acts after the enolase, so it will not be effective in the first 1 to 2 hours.
WebSodium fluoride inhibits glycolytic enzyme enolase, which limits ex vivo consumption of glucose in the specimen. Therefore, glucose in the gray top is stable for up to 24 hours. However, metabolism does occur at a rate of 5-7% for about 4 hours from the time of draw before complete inhibition of glycolysis. WebBecause of sodium fluoride and its experimental control, glycolysis was inhibited in tube 4. Due to the high temperature, glycolysis occurs at a very fast rate in tube 5. There is very little carbon dioxide created because the first tube did not contain any glucose.
