Quoted from the NIH: Normally, the immune system helps protect the body, but with Crohn's disease the immune system can't tell the difference between normal body tissue and foreign substances. The result is an overactive immune response that leads to chronic inflammation. This is called an autoimmune disorder..
Platelet Aggregation Test. A platelet aggregation test checks how well your platelets clump together. Platelets are types of blood cells. They help form blood clots by sticking together. A clot stops the bleeding when you have a wound. A platelet aggregation test requires a blood sample.The sample will be examined to see how the platelets are distributed through the plasma. Plasma is the liquid part of the blood. The lab technician will also add certain chemicals to your blood sample to test how quickly your platelets form a clot.latelets are types of blood cells.

Platelet aggregation. Thrombocytes are important for haemostasis and blood vessel repairs. They are also involved in inflammatory reactions. To perform these important tasks, platelets have the capability to interact with structures on the blood vessel walls.They adhere to the vessel wall and aggregate with each other on stimulation, aided by distinct receptors on their cell surfaces.linical significance. The most commonly used method for aggregation assessment is induced thrombocyte aggregation using the Born method. It utilizes platelet rich plasma (PRP) with addition of aggregation inducting substances (inductors) to measure photometric changes in an aggregometer.
