Magnesium RBC

Magnesium RBC (Red Blood Cell) testing measures the level of magnesium in a person's red blood cells. This test is often used to assess magnesium levels in the body, as red blood cells contain a higher concentration of magnesium compared to serum or plasma. Low levels of magnesium in red blood cells can indicate a deficiency in the body, while high levels may be seen in people with kidney disease or other conditions. This test can help diagnose and monitor magnesium status in patients.
