ABSTRACT:
There is provided an assay for determining the propensity of a person to develop a certain type of kidney stones which is based on the inter-action of the urine of such a person with aqueous solutions of compounds which interact to form such stones. The number and size distribution of resulting particles is determined and the results are evaluated. There is further provided a device for carrying out such an assay, comprising means for interacting the urine of the patient with two solutions containing compounds which form kidney stones, means for breaking up crystal aggregates and means for passing a light beam through the sample positioned in a transparent container, and means for determining the number and size of the resulting particles.
