Application of an anticoagulant to prevent clotting is a prerequisite for the retention of morphological integrity of platelets in blood samples. Among the anticoagulants used for the collection of blood from veterinary animals, are heparin, the oxalate salts (sodium and potassium) and di-sodium and tri-sodium citrates. In a study on the effects of anticoagulants on platelet morphology, it was noted that oxalates caused severe morphological distortion in platelets.

Clotting constituents become denatured in contact with the insoluble coagulant proteins. Quantities in excess of optimal modify plasma so that it does not gel when thrombin is added.
