“…The majority of studies report increased platelet aggregability, both in adults and children in response to various agonists: ADP [24,25,32,[34][35][36][37], collagen [25,31,32,[35][36][37][38][39], AA [26,34,35] and epinephrine [40], and increased platelet agglutination after stimulation with ristocetin [41] (Table 3). However, other studies could not find increased platelet aggregability in response to collagen [24], AA [25,26,32] and ristocetin [32].…”
