title: Use of Beckman BUN analysers to determine urine urea.
abstract: 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.
