(redirected from Nadi reaction)

per·ox·i·dase re·ac·tion

formation of indophenol blue by the action of an oxidizing enzyme present in certain cells and tissues when they are treated with a solution of α-naphthol and dimethylparaphenylenediamine; by this method, cells of the myelocyte series, which give a positive reaction, may be distinguished from those of the lymphocyte series, which give a negative reaction.
