Calcium is a vital mineral essential for building and maintaining strong bones and teeth, nerve function, muscle contractions, and blood clotting. While most calcium is stored in bones, a small amount circulates in the blood and is filtered by the kidneys. Some of this calcium is reabsorbed, while the rest is excreted in urine.
Measuring calcium in urine provides insights into bone health, kidney function, and metabolic activity. Abnormal levels of urinary calcium may indicate issues like kidney stones, metabolic imbalances, or underlying bone conditions.
