Urine calcium test
A urine calcium test is done to measure how much calcium is passed out of the body through urine. The test is also known as the urinary Ca+2 test.
Calcium is the most common mineral in the body. All cells throughout the body use calcium for various functions. Calcium is used by the body to build and repair bones and teeth. It also helps nerves, the heart, and muscles function properly, and blood to clot.
A urine calcium test measures the amount of calcium in a sample taken from all the urine that is produced in a 24–hour period. The test lasts from the morning of one day to the morning of the next day.
The amount of calcium in the urine of a person eating a normal diet is 100 to 300 mg/day*. A diet that is low in calcium results in 50 to 150 mg/day of calcium in the urine.
