The indirect platelet suspension immunofluorescence test in the detection of platelet antibodies in idiopathic thrombocytopenic purpura.
Among the various techniques developed for the detection of platelet antibodies, the platelet suspension immunofluorescence test has been reported to be simple, sensitive and reproducible, and therefore more clinically useful than other techniques available. An initial evaluation of the test was carried out for the detection of platelet autoantibodies in ten cases of idiopathic thrombocytopenic purpura. The indirect PSIFT was found to be positive in 60%. The technical aspects of the test and the problems encountered are discussed.
