The technique is proposed to evaluate cryoclobulins associated with IgM and IgG on the basis of detection of immune complexes circulating in healthy individuals and patients with liver cirrhosis. It is demonstrated that in patients with liver cirrhosis content of cryoclobulins associated with IgM increases almost twice and those associated with IgG more than two and a half times as compared with healthy individuals. It is established that in healthy individuals cryoclobulins are also present in blood in small amount. The proposed approach to detection of cryoclobulins permits to minimize time of implementation of study and also discharge of reagents.
