Clinical Significance
This assay is used for diagnosing and monitoring hypomagnesemia (magnesium deficiency) and hypermagnesemia (magnesium
excess). Numerous studies have shown a correlation between magnesium deficiency and changes in calcium- , potassium- and
phosphate-homeostasis which are associated with cardiac disorders such as ventricular arrhythmias that cannot be treated by
conventional therapy, increased sensitivity to digoxin, coronary artery spasms, and sudden death. Additional concurrent symptoms
include neuromuscular and neuropsychiatric disorders. Hypermagnesemia is found in acute and chronic renal failure, magnesium
excess, and magnesium release from the intracellular space.
