Calcium (Urine Test)

A calcium urine test measures the amount of calcium in the urine.

Calcium is an important mineral that plays a key role in bone health, muscle function, nerve function, and blood clotting. The body regulates the amount of calcium in the blood and excess calcium is excreted in the urine.

The test is typically done to evaluate the levels of calcium in the body and to help diagnose conditions related to calcium metabolism, such as hypercalcemia (high levels of calcium) or hypocalcemia (low levels of calcium).

A healthcare provider may order a calcium urine test if a person is experiencing symptoms of hypercalcemia or hypocalcemia, such as fatigue, muscle weakness, bone pain, kidney stones, or abnormal heart rhythm.

The test is done by collecting a sample of urine over a 24-hour period and sending it to a laboratory for analysis. It is important to follow the test provider's instructions for collecting and storing the urine sample to ensure accurate results.
