Walk-In Lab’s calcium urine test checks the amount of calcium that is passed from the body in 24 hours.

Fasting is not required when preparing for the calcium urine test, also known as a Ca or Urine test. Patients receive results within one to two days, and no insurance or doctor’s visit is required.

The calcium urine test from Walk-In Lab requires two visits to the lab, one to pick up the specimen collection kit and one to return the kit. The patient will void at 8 AM and discard the specimen, then collect all urine including the final specimen voided at the end of the 24-hour collection period, (at 8 AM the next morning).

As one of the most common and important minerals in the body, calcium is needed to build and fix bones and teeth, help blood clot and nerves work, make muscles squeeze together, and help the heart work. Most calcium in the body is stored in bone, while the rest is found in the blood. Blood calcium levels are normally carefully controlled, but when blood calcium levels get too low (hypocalcemia), the bones release calcium to bring it back to a good blood level. When blood calcium levels get too high (hypercalcemia), the extra calcium is stored in the bones or passed out of the body in stool and urine. Kidney stones may occur if calcium levels in the urine become too high.
