Method of enzymatic assay for creatinine or of the ammonium ion; the assembly of the reagents for óoeuvre.

摘要

The invention relates to a method of enzymatic assay for creatinine clearance, which consists in determining the quantity of ammonium ion released by creatinine clearance, characterized in that the determination is carried out in the presence of an acid hydroxamic or of one of its salts. & br / the invention also relates to a process for the elimination of errors in the enzymatic assay of the ammonium ion consisting in introducing into the reaction medium with the sample a hydroxamic acid or one of its salts. & br / the invention also relates to a set of reagents for the enzymatic assay for creatinine clearance, which comprises: & br / - of glutamate dehydrogenase (br / - creatinine iminohydrolase br / - of nadph br / - a salt of alpha - ketoglutaric br / - a solution of dilution br / - hydroxamic and an acid or one of its salts.
