Common mistakes around Magnesium Labor

A common mistake with magnesium lab tests is assuming that serum magnesium accurately reflects total body stores. In reality, only about 1% of magnesium circulates in the blood; the majority is stored in bones and cells. A normal serum level does not rule out intracellular deficiency. Many consumer blood tests measure only total serum magnesium, not the biologically active ionized form. Additionally, inflammation, kidney function, or medications can distort results. Another error is interpreting values without clinical symptoms (fatigue, muscle cramps, arrhythmias). The evidence is based on laboratory medicine practice, not randomized trials. Caveat: self-interpretation without a physician is risky; if deficiency is suspected, a doctor should evaluate the results in context.
