What this test is
This test measures the amount of magnesium in a urine sample, usually collected over a set number of hours or a full day. Magnesium is a mineral involved in muscle, nerve, and heart function, and urine levels reflect how much the body is removing. The test is often used alongside blood magnesium testing to get a fuller picture.
What it measures
- Urine magnesium — reflects the amount of magnesium excreted by the kidneys
- Collection volume — helps interpret the total magnesium output over the collection period
- Creatinine (if included) — used to assess how concentrated or dilute the urine sample is
What the test involves
You will collect all urine produced during a specified time frame, typically 24 hours, into a container provided by the lab. The lab may also request a single urine sample, depending on the reason for testing.
Why it is often ordered
A clinician may order this test to investigate symptoms such as muscle weakness, cramps, or irregular heartbeats that could relate to magnesium imbalance. It can also help monitor conditions or treatments that affect magnesium levels, such as kidney disorders or certain medications.
Preparation
