Peripheral blood smear morphologic review can evaluate for platelet clumping and granularity, as well as platelet number and size. A non anticoagulated peripheral smear in a patient. Laboratory findings consistent with the diagnosis of Glanzmann's thrombasthenia include prolonged bleeding time (BT) and failure of platelets plugging to the collagen-based filter in the PFA-100 test. Prevalence of GT is unknown but it is estimated to be about 1.1 million and it is encoun-tered in populations with a high rate of consanguinity [2].

What is the normal count of platelets. Basic coagulation tests, including prothrombin time (PT), partial thromboplastin time (PTT), and fibrinogen, are also part of the initial evaluation of a bleeding disorder. There should be normal platelet count and size with normal granularity on evaluation of the peripheral blood smear by light microscopy. Clinically, patients present with increased mucosal bleeding (epistaxis, menorrhagia, and/or post-op bleeding complications). Physicians Surg.
