Metabolic / Electrolytes
Also known as: Mg, Mag, Magnesium-Serum
Symptoms like severe muscle cramps, irregular heartbeat, or seizures, especially if magnesium levels are extremely low, warrant immediate medical attention. Cardiac arrest from extremely high magnesium levels is also an urgent flag.
This blood test checks how much magnesium is in your blood. Magnesium is a very important mineral. It helps your muscles, nerves, and heart work right. It also keeps your bones strong. Magnesium helps control your blood sugar and blood pressure too.
Your doctor orders this test to check your magnesium levels. They might think your levels are too high or too low. This test can also help find out why other minerals, like calcium and potassium, are unusual. Magnesium changes how your body uses these other minerals.
Reference ranges for magnesium levels can vary slightly between different laboratories. Your healthcare provider will interpret your results based on the specific reference range used by the lab.
