About the Magnesium Levels Blood Test - Deficiency
This blood test checks the level of magnesium in blood serum to evaluate deficiency or excess. Magnesium is a mineral involved in many biochemical reactions, including muscle and nerve function, energy production, and bone health. The test may be ordered for muscle cramps, weakness, irregular heartbeat, or when a person has a condition or takes a medicine that affects magnesium balance. Because most magnesium is stored in cells and bone, serum levels reflect only a portion of the body's total, so results are interpreted with clinical context.
What this test measures
- Magnesium (serum) Measures the amount of magnesium circulating in the blood.
Who this test may be right for
- People with muscle cramps, twitching, or weakness
- Individuals with an irregular heartbeat or palpitations
- People with conditions affecting nutrient absorption or kidney function
- Those taking medicines that can alter magnesium levels
Before your visit
- No fasting is usually required.
- Tell the collector about magnesium supplements or medicines you take.
- Follow any instructions provided for your specific panel.
Understanding your results
A low serum magnesium may suggest deficiency, which can relate to diet, absorption, or losses through the kidneys or gut. A high level may occur with excessive supplementation or impaired kidney function. Because serum magnesium does not capture all body stores, a normal result does not always rule out deficiency. Discuss results with a healthcare provider.
