Abstract
Blood cell aggregates are clinically useful biomarkers in a number of medical disorders. This protocol provides accurate and quantitative analysis of cell aggregates using a small volume of whole blood and imaging flow cytometry. We describe steps for sample collection, staining, and measurement. We then detail gating procedures and analysis of cell morphology. Sample preparation artifacts, activation, and morphological changes of cells are mitigated by omitting erythrocyte lysis and leukocyte isolation while maintaining high-throughput accurate imaging of leukocytes and platelets.
