Testing strategies used in the diagnosis of rare inherited bleeding disorders.

Recognition of RBD relies on obtaining a detailed patient's personal and family hemostatic history. Inquiry into a history of involvement of other organ systems is important and, if present, should lead to suspicion of an inherited platelet disorder or a variant of Ehlers-Danlos Syndrome. Multiple factors contribute to the complexity of developing efficient algorithms for diagnostic testing. Limitations in diagnostic sensitivity and specificity of screening tests, diagnostic tests, and esoteric tests further compound the complexity of establishing a diagnosis. Educational efforts focusing on clinician awareness of RBDs and available testing options are vital for optimal management of such patients.
