Platelet Aggregation Test. A platelet aggregationtest checks how well your platelets clump together.Platelets are types of blood cells. They help form blood clots by sticking together. A clot is what stops the bleeding when you have a wound. Platelet aggregation is part of the sequence of events leading to the formation of a thrombus (clot). Aspirin, the most commonly used antiplatelet drug changes the balance between prostacyclin (which inhibits platelet aggregation) and thromboxane (that promotes aggregation).
No special preparation is needed for Platelet Aggregation. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing Platelet Aggregation. Your doctor depending on your condition will give specific instructions.
