Magnesium in the blood - Magnesium (Mg), Serum

🧪 Magnesium analysis in blood This analysis measures the amount of magnesium in the blood, and it is an essential mineral that helps in muscle and nerve function, regulating heartbeats and blood pressure, and also has a role in bone formation and energy production. If the level is low, it could be due to: malnutrition, or fluid loss from vomiting or diarrhea, or use of diuretic medications. If it is high, it may indicate a kidney problem or excessive use of magnesium supplements. 🩺 Why does the doctor request the analysis? Usually requested with calcium and potassium tests if there is general fatigue, muscle cramps, or irregular heartbeat. 💡 Advice: It is preferable to do the analysis while fasting for 6 to 8 hours, and inform the doctor if you are using dietary supplements, as they may alter the result.
