BI041 - MAGNESIUM, SERUM Detail

Magnesium, Serum is an essential intracellular cation involved in numerous biochemical and physiological processes, including enzyme activity, energy metabolism, neuromuscular transmission, and maintenance of normal cardiac rhythm. The serum magnesium test measures the concentration of magnesium in the blood and is commonly performed using colorimetric or ion selective electrode methods. It is routinely used to assess electrolyte balance and to support the evaluation of renal function, gastrointestinal disorders, and metabolic disturbances. Altered magnesium levels may be associated with malnutrition, chronic alcoholism, malabsorption, prolonged diarrhea, renal disease, endocrine disorders, and use of certain medications such as diuretics. Measurement of serum magnesium is particularly important in patients with cardiac arrhythmias, neuromuscular symptoms, or unexplained electrolyte abnormalities, and it is often interpreted alongside calcium and potassium levels for comprehensive clinical assessment.
