Calcium in Urine Test

Introduction to Calcium in Urine Tests

Calcium in urine tests measure the amount of calcium that is being excreted in the urine. This test is used to help diagnose kidney problems, as well as other metabolic or hormonal disorders. The level of calcium in the urine can also indicate bone diseases, such as osteoporosis, and can help assess the risk of developing kidney stones and other calcium-related medical problems. In some cases, this test can be used to detect certain kinds of tumors.

Preparation and Procedure for Calcium in Urine Tests

No special preparation is required for this test. The sample will usually be collected in a clean container. The sample must be collected first thing in the morning, when the urine is concentrated and contains the most calcium. It is important to make sure the sample does not become contaminated by outside sources.

The sample will then be tested for the level of calcium in the urine. This is done using an automated system or an assay procedure. Depending on the results, further tests or a doctor visit may be required to diagnose the underlying cause.

Types of Calcium in Urine Tests

The two most common types of calcium in urine tests are a basic Metabolic Panel (BMP) or Complete Metabolic Panel (CMP). A BMP is typically used to measure the levels of electrolytes, kidney function, and calcium. A CMP is more specific and measures the levels of many different chemicals in the urine, including calcium. Both tests are minimally invasive and typically painless.

Risks of Calcium in Urine Tests

Calcium in urine tests are generally considered safe. There is no risk of serious complications, and the risk of infection is very low. Rarely, some people may have a reaction to the chemicals used to measure the calcium levels, but this is extremely rare.

Why is a Calcium in Urine Test Performed?

The calcium in urine test is typically ordered when a doctor suspects a patient may be suffering from: kidney problems such as stones, kidney failure or urinary tract infection; metabolic or hormonal disorders; or bone diseases such as osteoporosis. It can also be ordered to assess the risk of developing calcium-related medical conditions, or to detect certain kinds of tumors.

When is a Calcium in Urine Test Performed?

A calcium in urine test is typically ordered when a doctor suspects that a patient may be suffering from a condition related to calcium metabolism, or when the patient is at an increased risk for developing a condition such as kidney stones or bone diseases. It may also be ordered to follow up on a positive or abnormal results from other tests.
