Antiplateiet antibodies determination by indirect platelet adhesion inmunofluorescence in idiopatic thrombocytopenic purpuraThe indirect platelet adhesion immunofluoresccnce test was used to determine platelet antibodies in 36 patients with childhood idiopathic thrombocytopenic purpura (ITP), 20 acute and 16 chronic.Platelet antibodies were detected in 14/20 with the acute form and in 10/16 with the chronic form.The results obtained are similar to those of other authors with this technique as well as being independent of the platelet count at the moment of sampling tlte serum and of the previous 6 months transfusion records with blood products.The use of Hamax microtrays, taking advantage of using the platelct's capacity to adhere to glass surface, seems to increase the sensitivity of the test simplifying its procedure and increasing its efficiency.
