PRINCIPLE : Quick time is a global test to mesure activity of extrinsic coagulation factors (factors II, Vll, V and X). The principal consist to measure the clotting time of the patient's plasma and to compare it with that of a normal human plasma in presence of excess calcium and tissular thromboplastin.
