Quantitation of Serum Urea as Microcapillary Columns of Dixanthylurea

[摘要] A simple technic is proposed for direct estimation of urea in terms of columns of dixanthylurea precipitated from serum. The procedure is reproducible and yields results comparable to those obtained colorimetrically using normal and uremic sera. An equation has been derived which permits conversion of levels of dixanthylurea columns, in millimeters, to urea nitrogen concentrations. The new method is useful in detecting as well as monitoring cases of uremia.
