title: [Analysis of anti-platelet antibody].
abstract: Results obtained by analysis of anti-platelet antibody using flow cytometry (FCM) were as follows. The use of nest gating is useful in analysis of anti-platelet antibody and frequency of antibody production were 32.7% in patients with hematological disorders using FCM method. This method was much correlated to AHG-LCT method. The rate of coincidence was 92.1%. And effective rate of platelet transfusion of cross match carried out only by FCM method was 81.3%. Concentration of globulin fraction in patient's serum and avidin-biotin assay are useful for increasing the sensitivity of detection of anti-platelet antibody. Elimination of HLA (Class 1) antigen from platelet's surface is effective in both chloroquine and acid treatment. Background of fluorescent intensity was tendency to low by the acid treatment than by chloroquine one. It is possible that high titer serum of allogeneic anti-platelet specific antibody is able to be identified by means of its fluorescent intensity.
