About Magnesium RBC Test | Deficiency Testing in Downey
Magnesium is a mineral involved in hundreds of enzymatic reactions, including energy production, muscle contraction, nerve signaling, and bone structure.
Serum magnesium reflects only a small fraction of total body magnesium and can appear normal even when tissue stores are low. The red blood cell magnesium test instead assesses the magnesium concentration inside erythrocytes, which may provide a clearer view of long-term magnesium status.
Healthcare providers may order this test when symptoms such as muscle cramps, weakness, tremors, or irregular heart rhythms raise concern for magnesium deficiency. It can also be used to monitor conditions or medications that affect magnesium balance, including diuretic use, gastrointestinal disorders, and kidney disease.
Results are reported as a concentration of magnesium per volume of red blood cells. Reference ranges vary by laboratory, so results should be interpreted by a qualified healthcare professional alongside clinical history and other findings.
