Calcium, Urine 24H

Description

The Calcium, Urine 24H test measures the amount of calcium excreted in the urine over a 24-hour period. This test is important for evaluating calcium metabolism and kidney function. It’s particularly useful in assessing the risk of kidney stone formation, diagnosing certain types of kidney stones, and evaluating bone disorders that affect calcium balance. Elevated urine calcium levels may indicate conditions such as hyperparathyroidism, excessive vitamin D intake, or certain medications affecting calcium metabolism. Conversely, low levels might suggest vitamin D deficiency or problems with calcium absorption. This test is often used in conjunction with blood calcium tests for a comprehensive evaluation of calcium homeostasis.
