[Automatic assay of plasma and urinary calcium, inorganic phosphate, creatinine and uric acid. Comparison between continuous flow analysis on a single microsample and low speed centrifugation].

A device is described allowing the association on a single microsample of assay by means of continuous flow analysis. The preparation of standards, the evaluation citeria of the method are presented. The preparation of standards, the evaluation criteria of the method are presented. The results are compared to those obtained by low speed centrifugation, i.e. by means of quite different analytical prinicples -- both dynamics and chemicals. These results are discussed : they allow to observe, as a whole, an excellent concordance.
