[Kinetic determination of urea with the LKB system (author's transl)].

The kinetic determination of urea based on the urea/glutamate dehydrogenase method was adapted for the LKB Reaction Rate Analyzer System 8600. A ratio of sample to reagent volume of 1:50 ensures linearity up to 33.3 mmol/l with a day to day precision of 5%. Parallel studies with the urease/glutamate dehydrogenase method were performed with the CentrifiChem System and with the manual Berthelot/Salicylate method.
