One hundred and twenty four tests of quantification of platelet associated IgG were done in patients with thrombocytopenia. The level was increased in 80% of the patients with ITP. The platelet associated IgG level does not seem a prognosis tool but is useful to follow the evolution. Platelet associated IgG levels higher than 600 x 10(-16) g/platelet were only observed in ITP (control less than 54 x 10(-16) g/platelet). Level lower than 600 x 10(-16) g/platelet were observed in systemic lupus erythematosus, chronic lymphocytic leukemia or chronic hepatitis. In defective thrombopoïesis, the levels were always normal.
