Use of Beckman BUN analysers to determine urine urea. 1979

H M Heick, and A Mohammed, and L Murzello, and N Bégin-Heick

In this paper we report a method to enable the Beckman BUN analyser to be used for urine urea nitrogen determinations. Satisfactory urine samples could be obtained by diluting the urine with 10 volumes of 0.85% saline. We also report our experience with the use of reagent prepared in house and with a modified pipette, to reduce the cost of using the instrument.

UI MeSH Term Description Entries
D001806 Blood Urea Nitrogen The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.
