This test measures the concentration of magnesium, an essential mineral involved in muscle, nerve, and enzyme function.
Diagnostic Value: Low magnesium (hypomagnesemia) may result from poor diet, alcohol use, or diuretic therapy, while high magnesium (hypermagnesemia) may indicate kidney dysfunction.
Clinical Significance: Magnesium testing is critical for evaluating muscle cramps, arrhythmias, or electrolyte disturbances.
Symptom Correlation: Abnormal levels can cause weakness, irregular heartbeat, tremors, or confusion.
Because magnesium is vital for cellular energy and nerve function, its measurement is key to assessing metabolic and cardiovascular stability.
