The buccal mucosal bleeding time is a simple test that gives a rapid assessment of platelet function, providing platelet numbers are normal. If platelet numbers are below 50x109/l, this test should not be performed since the results will be affected by thrombocytopenia, making them unreliable.
Blood Clots: Plugging the Breaks. When an injury causes a blood vessel wall to break, platelets are activated. They change shape from round to spiny, stick to the broken vessel wall and each other, and begin to plug the break. They also interact with other blood proteins to form fibrin. Fibrin strands form a net that entraps more platelets and blood cells, producing a clot that plugs the break. Formation of a clot also involves activation of a sequence of blood clotting factors that generate thrombin.
