Red Cell magnesium

The test is typically ordered for individuals who might be experiencing symptoms of a magnesium deficiency. These symptoms can include cardiac arrhythmias, seizures, muscle cramping, and weakness. Additionally, those with conditions like malnourishment, alcoholism, anorexia or bulimia nervosa, diabetes, and certain gastrointestinal disorders might also be recommended for this test.

Test results are generally reported in millimoles per liter (mmol/L). A standard reference range for magnesium levels in red blood cells is between 10 and 40 mmol/L. If levels are outside this range, it may indicate a magnesium deficiency or an excess. Lower levels can be indicative of conditions like malnourishment, prolonged use of diuretics, or gastrointestinal disorders. Elevated levels might suggest issues related to kidney failure, thyroid disorders, or the intake of certain medications containing magnesium.
Interpretation of the results depends on whether the magnesium level is too high or too low:

1. Low magnesium levels (hypomagnesemia): A low level of magnesium in the blood may indicate a deficiency, which can be caused by various factors such as malnutrition, alcoholism, or certain medications. Symptoms of hypomagnesemia include muscle weakness, fatigue, and irregular heartbeat.

- Mild hypomagnesemia: 1.2-1.6 mg/dL or 0.5-0.65 mmol/L
- Moderate hypomagnesemia: 0.9-1.2 mg/dL or 0.4-0.5 mmol/L
- Severe hypomagnesemia: <0.9 mg/dL or <0.4 mmol/L

2. High magnesium levels (hypermagnesemia): High levels of magnesium in the blood may indicate excessive use of supplements or certain medications, kidney disease, or other medical conditions.

- Mild hypermagnesemia: >2.3 mg/dL or >0.95 mmol/L
- Moderate hypermagnesemia: >3 mg/dL or >1.25 mmol/L
- Severe hypermagnesemia: >4 mg/dL or >1.65 mmol/L

You should always have your results interpreted by a healthcare professional who has access to your complete medical history and other relevant information.

In general, the Magnesium Blood Test is a valuable tool for diagnosing and managing various medical conditions related to abnormal levels of magnesium in the body. The results of this test can provide valuable information to healthcare professionals about a patient's overall health and help them diagnose and treat any underlying medical conditions related to magnesium deficiency or excess.
