To reduce the complexity and risk associated with activated platelet transfusions, thrombocytopenic patients are transfused with exclusively non-activated platelets. A preferred embodiment is through routine screening of platelet units in the hospital blood bank using dynamic light scattering and selective allocation of platelets, with non-activated platelets being exclusively transfused to thrombocytopenic patients, especially patients with cancers such as hematologic malignancies. Activated platelets typically contain activated factors of the innate immune system called complement, transforming growth factor beta (TGF&#x3b2;), interleukin 6 (IL-6), CD40 ligand (CD40L) and C-reactive protein (CRP) for example. Some of these activated factors have already been shown to correlate with microparticles and others are expected to correlate: the higher the platelet activation the more microparticles and the higher the concentration of these factors. By transfusing only non-activated platelets, therapeutic outcomes are enhanced.
