Age Group	Reference Range	Unit	Notes
Adults (18–64)	1.7 – 2.2	mg/dL	—

Also reported in: mmol/L.

Critical (Panic) Values

Critical Low: < 1 mg/dL. Critical High: > 4.9 mg/dL. Values outside these limits require immediate clinical attention.

Common Causes of High Mg

Renal failure (most common — reduced excretion)Excessive magnesium supplementation or antacid useIntravenous magnesium therapy (pre-eclampsia treatment)

Common Causes of Low Mg

Chronic diarrhea and malabsorption (most common GI cause)Proton pump inhibitors (PPIs) — can cause renal magnesium wasting with long-term useDiuretics (loop and thiazide — increase renal magnesium excretion)
