[Solid-phase conglutinin tests for circulating IgA immunocomplexes]

In some renal, gastroenterological and dermatological diseases the pathogenic role of circulating immune complexes (CIC) of IgA type has been defined. The methods so far proposed to investigate CIC are for the most part able to identify IgGIC, while only few can do the same for IgAIC. The Authors discuss in details the technique and the sensibility and specificity of a new test for IgAIC based on the linkage with the conglutinin in solid phase and propose this test for the clinical study of IgA diseases.
