In evaluating patients for defects of hemostasis, the clinical context must be considered carefully. Heritable defects are suggested by bleeding that begins in infancy or childhood, is recurrent, and occurs at multiple anatomic sites, although many other patterns of
presentation are possible. Acquired disorders of hemostasis more typically are associated with bleeding that begins later in life and may be relatable to introduction of medications (eg, agents that affect platelet activity) or to onset of underlying medical conditions (such as kidney disease, liver disease, myelodysplasia), or may be idiopathic. Importantly, however, a sufficient hemostatic challenge (such as major trauma) may produce excessive bleeding even in individuals with completely normal hemostasis. A personal history for hemostatic challenges (eg, circumcision, trauma, injury during youth sports, tooth extractions, motor vehicle accidents, prior surgery, and pregnancy and delivery) is critical for evaluating a patient for a possible bleeding disorder.
