Magnesium
Blood level does not show your stores.
The typical serum magnesium range is about 0.70–0.95 mmol/L (1.7–2.3 mg/dL). Less than 1% of body magnesium is in blood, so a normal value does not show full stores.
| Serum (mmol/L) | Meaning |
|---|---|
| <0.70 | Low (hypomagnesemia) |
| 0.70–0.95 | Typical range |
| >1.05 | High; mostly kidney failure or excess supplements/medicines |
