[The Sarig test. A simple method to evaluate the inhibitory effect on urinary crystallization of calcium oxalate].
In this study, the Authors evaluate a simple test proposed by Sarig for the discrimination of kidney stone-formers, based on the overall urine inhibitory effect. A solution of the tested urine is added with sodium-oxalate and the kinetics of calcium-oxalate precipitation is indirectly followed with ionometric selective measurement of the progressive reduction of free calcium ions. A Discriminating Index may be therefore calculated; higher values are obtained in lithiasic patients in comparison with normal controls.
