Evaluation of a possible hemostatic disorder in each of these scenarios is a stepwise process that requires knowledge of the various classes of hemostatic disorders commonly found under the particular circumstances. The patient’s history, the results of physical examination, and an initial set of hemostatic tests usually enable a tentative diagnosis. However, more specific tests are commonly necessary to make a definitive diagnosis. This chapter reviews the necessary steps.
