“…Studies using thrombin generation assays (TGAs) found a correlation between TG parameters and the factor activity level [ [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] ]. In addition, previous studies suggested that the TG profile better determines which hemophilia patients are at increased risk of bleeding [ 3 , 4 , 7 , 8 , [11] , [12] , [13] , [14] , [15] , [16] , [17] ]. A decreased thrombin peak height and thrombin potential were found in patients with a severe clinical bleeding phenotype irrespective of the FVIII or FIX activity level.…”
