SERUM MAGNESIUM
The Serum Magnesium test measures the level of magnesium in the blood, an essential mineral involved in many vital body functions. Magnesium plays a key role in muscle and nerve function, maintaining normal heart rhythm, supporting bone health, and regulating blood sugar and blood pressure.
Abnormal magnesium levels can affect overall health. Low magnesium levels (hypomagnesemia) may cause muscle cramps, weakness, tremors, irregular heartbeat, or seizures and can be seen in conditions like malnutrition, alcoholism, or gastrointestinal disorders. High magnesium levels (hypermagnesemia) are less common but may occur in kidney disease or excessive intake and can lead to nausea, low blood pressure, or cardiac issues. Doctors often recommend this test to assess electrolyte balance and monitor certain medical conditions.
The Serum Magnesium test is simple and requires a small blood sample. Accurate results help doctors diagnose electrolyte imbalances, monitor treatment, and ensure proper management of a patient’s health.
