Urea determination of biological fluids using diacetylmonoxime reaction

摘要

A unique composition and method for the determination of urea using diacetylmonoxime and thiosemicarbazide in an aqueous strong acid to which has been added a color-intensifying amount of a cation selected from the group consisting of ferric and ceric; and a linearity-enhancing amount of 4-amino-antipyrine.
