A new screening test for the diagnosis of mucopolysaccharidoses

A simple method for the electrophoretic separation of glycosaminoglycans from untreated urine is presented. It is shown that this rapid electrophoresis on specially shaped acetate cellulose strips gives more information than other screening tests used in laboratory for discriminating between normal and pathological samples. This technique is useful particularly with low levels of glycosaminoglycans which may give false-negative responses.
