title: [Conductometric microdosage of blood and urine urea by use of a semi-automatic analyser].
abstract: The authors present the principle of a new method of urea estimation based on conductimetry. Its results are compared with those given by the colorimetric method using diacetylmonoxime. Correlation of the results was satisfactory. With the apparatus studied, it was possible to estimate very simply plasma and urinary urea with low volume samples 10 microliter). The titration took 30 seconds.
