RESUMO

Salicylate concentrations in 3819 sera of apparently healthy voluntary blood donors were determined in view of the significance of this drug in the induction of allergic reactions and its possible interference in platelet function. Two hundred and ninety-five sera were found by a modified colorimetric determination to contain salicylates. The colorimetric determination was compared with a high performance liquid chromatography (HPLC) analysis of salicylate-containing sera. Drug concentrations detected were mostly in the range of 20-100 mg/l. Such concentrations have been reported to evoke allergic reactions and to affect the haemostatic action of platelets.
