CALCIUM, 24 HRS URINE

Calcium, 24 Hrs Urine

What it is

The Calcium 24-hour urine test measures the amount of calcium excreted in the urine over a 24-hour period. Calcium is essential for healthy bones, muscles, and nerve function. Abnormal levels in urine may indicate kidney problems, bone disorders, or issues with calcium metabolism.

Uses

This test helps in diagnosing conditions that affect calcium balance in the body. It is commonly used to evaluate kidney stone risk, monitor parathyroid gland function, detect metabolic bone diseases, and assess calcium metabolism disorders.

Symptoms That May Lead to the Test

Doctors may recommend this test if you have frequent kidney stones, bone pain, muscle weakness, unexplained fractures, fatigue, or suspected parathyroid or metabolic disorders.

Abnormal Results

High Calcium in Urine (Hypercalciuria): May indicate kidney stones, hyperparathyroidism, excessive vitamin D intake, or bone disorders such as osteoporosis or Paget’s disease.

Low Calcium in Urine (Hypocalciuria): May suggest kidney disease, low dietary calcium, vitamin D deficiency, or certain hormonal imbalances.

Risks

The test involves collecting urine for 24 hours and has no direct risks. It may be slightly inconvenient for patients, but there are no complications since it is a non-invasive test.
