# How Sodium Citrate Blood Collection Tubes Work

Sodium citrate prevents blood clotting by **reversibly binding calcium ions**, preserving coagulation proteins in their functional state. During laboratory testing, calcium is added back to the plasma, allowing coagulation reactions to occur under controlled conditions. This makes sodium citrate the preferred anticoagulant for coagulation assays.

Accurate results depend on filling the tube to its intended volume to maintain the correct blood-to-anticoagulant ratio.
