Contribution of Anti-platelet Antibodies Identified With MAIPA Assay in the Demonstration of the Auto-immune Character of a Thrombocytopenia at Diagnosis

"* Thrombopoietin : 7 ml whole blood.~* Anti-platelet antibodies free : 14 ml whole blood.~* Anti-platelet antibodies bound :~If the platelet count is ≥ 50 G / L : 14 ml whole blood for Peripheral blood mononuclear cell (PBMC) and monocytes isolation ; If the platelet count is \< 50 G / L and ≥ 20 G / L : 28 ml whole blood for Peripheral blood mononuclear cell (PBMC) and monocytes isolation ; If the platelet count is \< 20 G / L and ≥ 10 G / L: 42 ml whole blood for Peripheral blood mononuclear cell (PBMC) and monocytes isolation ; If the platelet count is \< 10 G / L : 49 ml whole blood for Peripheral blood mononuclear cell (PBMC) and monocytes isolation."
