Reagent mixture for determination of albumen in biological fluid, useful for early diagnosis of e.g. kidney disease, includes polysaccharide, disaccharide and boric acid

摘要

Reagent mixture (A) for determination of albumen (I) in body fluids, especially urine, contains, apart from known antibodies (Ab), additives and buffers, at least one polysaccharide (II), at least one disaccharide (III) and boric acid (IV), is new. An independent claim is also included for a test kit for determining (I) that comprises (A) and stable formazin suspensions, as turbidity standards for semi-quantitative determination of (I), standardized for visual or nephelometric determination of optical densities that correspond to the turbidity of (I)-Ab complexes.
