FIELD: analytical biochemistry, polymers. SUBSTANCE: invention proposes new sorbent for affinity assay of the glycosylated hemoglobin. High effectiveness of sorbent by ligand (above 20-fold use of 1 ml sorbent) is provided by the presence of cross-linked polyvinyl alcohol with the immobilized m-aminophenylboronic acid of the general formula given in description where amount of m-aminophenylboronic acid in sorbent is 0.37-1.49%, molecular mass of an active chain of cross-linked polyvinyl alcohol is 2·I03÷3·I03, Da, swelling coefficient is 80-100%. Sorbent can be used in medicine for diagnosis and course severity of diabetus mellitus. EFFECT: improved quality and property of sorbent. 3 tbl
