The ratio of blood to anticoagulant is critical for valid coagulation test results. If there is incomplete filling of the sample tube, the amount of unbound citrate in the citrate-plasma mixture causes a false prolongation of clotting times, particularly in PT and PTT tests. Likewise, if the tube is overfilled, the result may be falsely shortened.

Disseminated Intravscular Coagulation. Whole Blood Clotting Time. Is a very crude test done to determine whether there is any clotting defect. Method :-5 ml of blood is collected by venepuncture. This is put in a glass tube and timing is started. The glass tube is tilted at intervals to check if the blood …
