Clinical Interest
Magnesium plays an essential role in many physiological processes, such as muscle function, nerve transmission, bone structure and energy production.
The kidneys play an important role in regulating magnesium levels. The urinary excretion of magnesium is closely linked to kidney function.
- Hypomagnesaemia: If serum magnesium levels are low, a urinary magnesium assay can help determine whether the cause is due to excessive renal loss or inadequate dietary intake or absorption.
- Hypermagnesaemia: High serum magnesium levels can result from increased intake (e.g. supplementation) or renal failure.
Low magnesium levels can lead to neuromuscular and cardiovascular problems, such as muscle cramps, arrhythmias and seizures. A urinary magnesium assay can be used to determine whether magnesium supplementation is necessary in such cases.
