title: Platelet-associated IgG assay using flow cytometric analysis.
abstract: In this study we describe an immunofluorescent assay system to measure platelet-associated immunoglobulin G levels using flow cytometric analysis. This semi-quantitative system allows ready distinction of immune from non-immune related thrombocytopenias. It is simple to perform, highly reproducible and has the advantage of requiring a minimum concentration of 5000 platelets/microliter per assay sample.
