RT Journal Article SR Electronic T1 A RAPID AND PRECISE METHOD FOR THE DETERMINATION OF UREA JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 156 OP 159 DO 10.1136/jcp.13.2.156 VO 13 IS 2 A1 J. K. Fawcett A1 J. E. Scott YR 1960 UL http://jcp.bmj.com/content/13/2/156.abstract AB A method is described for the determination of urea in plasma and urine. The effects of variations in the experimental conditions are examined and the results of recovery experiments and other tests of precision and accuracy are reported. In comparison with other methods in current use, this method has distinct advantages in sensitivity, simplicity, and precision, thus economizing in time, sample volume, reagents, and equipment.
