- What Does a High Platelet Count Mean? A platelet count over 450,000/mcL is called thrombocytosis. A higher-than-normal platelet count can cause blood clots to form and lead to a condition called acquired von Willebrand disease. In this disease, the platelets fail to interact properly with the blood vessel wall at sites of injury.

Thrombocytosis occurs when your body produces too many platelets.
Essential thrombocythemia can lead to a variety of potentially life-threatening complications, such as: 1. Strokes.If a blood clot occurs in the arteries that supply the brain, it may cause a stroke. A mini stroke, also called a transient ischemic attack, is a temporary interruption of blood flow to part of the brain. 2. Heart attacks.Less commonly...
