Glanzmann's thrombasthenia

Summary of Glanzmann's thrombasthenia
Glanzmann's thrombasthenia is an abnormality of the platelets. It is an extremely rare coagulopathy in which the platelets contain defective or low levels of glycoprotein IIb/IIIa, which is a receptor for fibrinogen. As a result, no fibrinogen bridging of platelets to other platelets can occur, and the bleeding time is significantly prolonged.
