The “Calcium in Urine” test checks the amount of calcium that is passed away from the body into the urine. The test is a 24 – hour long procedure. Calcium plays a crucial role in the body. It facilitates the growth and development of muscles, bones and teeth. Calcium levels in the body are controlled through well planned mechanisms. A urine calcium test detects the presence of kidney stones due to an extra amount of calcium in the body. It also checks the absorption power of intestinal tubes. Allied problems that lead to the loss of calcium from the bones are checked. Issues with the parathyroid glands get highlighted through a urine calcium test.
