Serum magnesium level refers to the concentration of magnesium found in a sample of blood serum, which is the clear yellowish fluid obtained after the blood has coagulated. Magnesium is an essential mineral that performs numerous important functions in the body. It is involved in the formation and maintenance of healthy bones and teeth, supports proper muscle and nerve function, and plays a role in energy production, protein synthesis, and DNA synthesis.
Measuring serum magnesium level is an important diagnostic test that helps healthcare professionals assess a person's magnesium status. It is particularly useful in identifying magnesium deficiencies or excesses, which can contribute to various health problems. Low serum magnesium levels, known as hypomagnesemia, can lead to symptoms such as muscle weakness, fatigue, numbness, irregular heartbeat, and changes in mood. On the other hand, excessively high serum magnesium levels, called hypermagnesemia, may cause symptoms like nausea, vomiting, muscle weakness, low blood pressure, and in severe cases, cardiac arrest.
Monitoring serum magnesium levels is crucial for individuals with certain health conditions like kidney disease, diabetes, gastrointestinal disorders, and alcoholism, as these conditions increase the risk of magnesium imbalance. Regularly checking serum magnesium levels helps doctors determine the need for magnesium supplements or treatment adjustments to prevent complications and maintain optimal health.
