Platelets are the smallest cellular component in the circulation. The primary role of circulating platelets is to maintain hemostasis. The evaluation of platelets by flow cytometry has proven beneficial in the investigation of many disease states including inherited defects, cardiovascular disease including stroke, and many other inflammatory processes. Flow cytometry can be used to evaluate platelet surface glycoproteins, platelet activation status, and platelet responsiveness to agonists. Appropriate sample handling, reagent preparation, flow cytometric set-up, and data interpretation are critical for generating reproducible results of platelet surface receptor expression and evaluating platelet-derived microparticles, pro-coagulant platelets, and leukocyte-platelet aggregates. Key elements of platelet sample preparation are described here. For a more complete description of flow cytometric protocols used in the evaluation of platelet function see Krueger LA et al. Immunophenotypic Analysis of Platelets, Current Protocols in Cytometry (2002) 6.10.1 - 6.10.17.
