| Usage: |
This assay is used for differentiating absorptive from nonabsorptive causes of hypercalciuria. Therapy for hypercalciuria depends upon the cause. Hypercalciuria due to absorptive causes usually responds to dietary restriction whereas hypercalciuria from other mechanisms usually responds to Thiazides. |
