Abstract
A method is provided for diagnosing a patient's proneness to develop kidney stones of the calcium oxalate type, which comprises forming an aqueous reaction medium comprising from about 5 to about 20% by volume of a sample of the patient's urine, said medium having an ionic strength of from about 0.01 to about 0.1 and containing calcium ions at a concentration of from about 1 to about 5 mM/l and oxalate ions at a concentration of from about 1 to about 7 mM/l; measuring by means of a calcium ion-specific electrode the rate of decrease of the calcium ion concentration and comparing the thus measured rate with the corresponding rate determined with a reference sample of normal urine. A kit for carrying out the above method is also provided.
