They provide a single measure of aggregation (an endpoint) rather than a measure of aggregation over time. More platelets aggregating or sticking to beads indicates better platelet function. These tests may be abnormal if the platelet count is low, if platelet function is reduced, or if anti-platelet medications are present. Platelet count ratio

Platelet aggregation is a crucial step in the process of clot formation, which stops bleeding. A platelet aggregation test can be performed to determine how well platelets are sticking together. The test measures this by using a platelet antagonist to initiate clumping in the patient's blood sample. The most common platelet antagonists are ADP ...

aggregation of platelets by AA and PAF at an IC50 of m mol shown by (Figure 4). Discussion Both AA and PAF are potent mediators of platelet aggregation. Platelet membrane contains receptors for PAF while AA exerts its effects through its metabolite thromboxane A2. Many studies suggest the central role of Ca++ in platelet aggregation process.
