Despite major differences in the levels of individual components of the hemostatic system, neonatal coagulation is equal to or somewhat more rapid than that observed in adults. This suggests the existence of a delicately balanced hemostatic system in neonates, with uncommon bleeding or thrombosis in healthy term infants. However, a number of perinatal or neonatal conditions can disrupt this balance and increase the risk for either hemorrhage or thrombus formation. The presence of bleeding in a healthy term or late preterm infant, especially in an infant with a normal platelet count, is strongly suggestive of a congenital bleeding disorder. Hemophilia A and B and von Willebrand disease account for 95–98% of congenital bleeding disorders.
