Biomarker Reference · Mg
Intracellular Magnesium (Mg) is a clinical biomarker used in comprehensive-panels assessment. Magnesium is the second most abundant intracellular cation and a cofactor for more than 300 enzymes, including those in ATP synthesis, nucleic-acid stability, and membrane function. It is measured in 2 laboratory tests on BiomarkersLabs.com.
Magnesium is the second most abundant intracellular cation and a cofactor for more than 300 enzymes, including those in ATP synthesis, nucleic-acid stability, and membrane function. Serum magnesium is tightly regulated and may be normal despite tissue depletion, so intracellular measurement is offered as a functional marker.
Magnesium insufficiency contributes to muscle cramps, arrhythmia, hypertension, insulin resistance, and neuropsychiatric symptoms. Cellular testing may detect functional deficiency missed by serum magnesium, particularly in chronic stress, gastrointestinal loss, or medication use (diuretics, proton pump inhibitors).
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
