The majority of patients with clinical manifestations of magnesium deficiency have hypomagnesemia. Magnesium assessment can also be made via the following, which are mostly limited to research purposes.

  • Red cell content
  • Mononuclear cell content
  • Skeletal muscle intracellular content
  • 24-hour urinary excretion
  • Fractional excretion (FE) of magnesium
  • Intracellular free magnesium ion concentration with fluorescent dye or nuclear magnetic resonance spectroscopy
