This tool estimates the percentage of filtered calcium excreted in urine. It requires serum and urine calcium and creatinine measurements, facilitating assessment of calcium homeostasis. For example, it can differentiate between various causes of hypercalcemia, such as primary hyperparathyroidism or familial hypocalciuric hypercalcemia, based on how the kidneys handle calcium.
Evaluating renal calcium handling offers crucial diagnostic insights for conditions affecting calcium balance. Historically, this involved complex manual calculations. Automated tools simplify this process, enabling rapid and accurate assessment, which is particularly valuable in acute settings. This information contributes to a more comprehensive understanding of a patient’s mineral metabolism and guides appropriate therapeutic interventions.
