Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

In plain language

What this test helps you understand

This test helps evaluate calcium metabolism, assess kidney function related to calcium handling, and investigate potential causes of bone disorders or kidney stones. It can aid in diagnosing conditions like hypercalciuria (excess calcium in urine) or hypocalciuria (low calcium in urine).

The Calcium Excretion 2 Hour Fasting Urine Test is a diagnostic tool used to evaluate how your body processes calcium. It measures the amount of calcium excreted in your urine over a specific two-hour period after fasting. This test provides valuable information about calcium metabolism and can help identify potential issues related to bone health, kidney function, and calcium balance. It is particularly useful for individuals concerned about bone density, kidney stones, or other conditions affecting calcium levels. Understanding your calcium excretion can help your doctor make informed decisions about your health.

Questions people ask

Frequently asked questions

Fasting ensures that the test measures baseline calcium excretion without interference from recent food or drink intake, providing a more accurate result.

High calcium excretion (hypercalciuria) can be associated with conditions like kidney stones, osteoporosis, or hyperparathyroidism. Your doctor will interpret this in context.

Low calcium excretion (hypocalciuria) can sometimes be seen in conditions affecting calcium absorption or certain kidney disorders. Your doctor will interpret this in context.

Specific instructions are provided to ensure accuracy. You will need to collect urine at a precise time after fasting and drinking specific amounts of water. Follow the instructions carefully.

No, the test involves providing a urine sample, which is not painful.
