Gray-topped evacuated collection tubes usually contain_____________.
- Ethylenediamine tetra-acetic acid EDTA
- Sodium citrate
- Potassioum oxalate and sodium fluoride
- Glass beads
Correct Answer

A. Potassioum oxalate and sodium fluoride

Explanation

Gray-topped evacuated collection tubes usually contain potassium oxalate and sodium fluoride. These substances are added to the tubes to prevent the blood from clotting. Potassium oxalate acts as an anticoagulant by binding to calcium ions, which are necessary for the blood to clot. Sodium fluoride is a glycolysis inhibitor that prevents the breakdown of glucose in the blood. By inhibiting glycolysis, sodium fluoride helps preserve the glucose levels in the blood for accurate testing.
