BACKGROUND: Coagulation factor XIII deficiency, in either its acquired or inherited form, is a rare cause of abnormal bleeding. In patients with Factor XIII (F XIII) deficiency, recommended means of factor replacement include infusion of fresh frozen plasma (FFP), cryoprecipitated plasma (Cryo), or F XIII concentrates1. Comparisons of F XIII concentration in FFP and Cryo are not well defined. To aid management of F XIII deficiency, we measured F XIII activity and antigen in FFP and Cryo. In addition, we determined concentrations of fibrinogen, factor VIII (F VIII) and von Willebrand factor (VWF), including antigen (VWF:Ag), ristocetin cofactor activity (VWF:RCo) and collagen binding activity (VWF:CB). STUDY DESIGNS AND METHODS: 10 bags each of FFP and of Cryo from blood group O donors obtained from the Mayo Clinic Division of Transfusion Medicine blood bank, were analyzed. F XIII activity was assayed by ELISA detecting activated F XIII-mediated amine incorporation into solid phase fibrinogen (Pefakit, Pentapharm). F XIII antigen was measured using radial immunodiffusion (The Binding Site). Fibrinogen was measured by Clauss kinetic clotting assay (Fibriquik, Biomerieux) and also by endpoint delta OD derived from the prothrombin time (ACL, Instrumentation Lab). F VIII was measured by 1-stage APTT-based assay; VWF:Ag by automated LIA (Diagnostica Stago); VWF:RCo by aggregometry of washed platelets; and VWF:CB by ELISA (Corgenix). RESULTS: Mean concentrations of F XIII activity were 60 U/bag (+/−30) in Cryo and 288 U/bag (+/− 77) in FFP. F XIII antigen concentrations paralleled the activity results and are depicted in Table 1, which also includes results for the other analytes. The mean fluid volumes of Cryo and FFP were 21.3 ml/bag (+/− 2.7) and 245 mL/bag (+/− 29), respectively.
