Using sodium citrate: blood collection tube

Sodium citrate exerts its anticoagulant effect by chelating calcium ions in blood samples. The National Committee for Clinical Laboratory Standards (NCCLS) recommends a concentration of 3.2% or 3.8%, with an anticoagulant to blood ratio of 1:9. It is primarily used for the fibrinolytic system (prothrombin time, thrombin time, activated partial thromboplastin time, and fibrinogen).
