Cautions
The urine is often supersaturated with respect to the common crystalline constituents of stones, even in nonstone formers.
Individual interpretation of the supersaturation values in light of the clinical situation is critical. In particular, treatment may reduce the supersaturation with respect to one crystal type, but increase the supersaturation with respect to another. Therefore, the specific goals of treatment must be considered when interpreting the test results.
