Method for the specific determination of serum fructosamine content and suitable reagent mixture

摘要

The present invention relates to a method for the specific determination of the serum fructosamine content in blood or blood-derived samples by reaction with a suitable color reagent and measurement of the color change caused thereby. The method according to the invention is characterized in that, before the color reaction, nonspecificly reducing or / and turbidity-causing sample components are removed at an approximately neutral pH value, then a pH value between pH 10 and 12 is set and the color reagent is added. Another object of the invention is a reagent mixture for the specific determination of the serum fructosamine content in blood or blood-derived samples, which is characterized in that it consists of a reagent for the removal of nonspecifically reducing and / or turbidity-causing sample components, a re-buffering reagent with a buffer, the one Has pH in the range of l0.5 to l2.5 and a color reagent for the detection of fructosamine.
