[Microdetermination to creatinine in biological fluids by kinetic methods. Comparison with continuous flow methods].

The authors compare the performances of two micromethods of determination of creatinine in biological fluids, based on the measurement of the kinetics of the reaction of Jaffe: one was adapted to an analyser of the rate of reaction LKB 8 600, the other, a rapid analyser by centrifugation, the Centrifichem. Correlations with continuous flow techniques with dialysis are also reported.
