Case Study Three, continued
Initial aPTT | Immediate aPTT mixing study | Incubated aPTT mixing study |
63 sec. (normal range 21-34 seconds) | 26 sec. | 65 sec. |
Has the aPTT been corrected by the mix? Is a factor deficiency or a coagulation inhibitor the more likely cause of the patient's prolonged aPTT?
