Detailed description
Glanzmann thrombasthenia (GT) is a blood clotting disorder that occurs in two different forms. They differ in the amount of certain glycoproteins (αIIbβ3) embedded in the cell membrane of thrombocytes, which are necessary for clotting.
In the more severe type I GT, detected by this test, the value is less than 5% of normal. A variant in the αIIb gene disrupts the formation of a major component of these glycoproteins. Symptomatically, the bleeding tendency usually becomes apparent through continuous bleeding of the gums after the loss of the milk teeth. Persistent nosebleeds can also be an indication of this disorder.
