Description

Magnesium is a crucial trace element in our body. This test measures magnesium levels in red blood cells, helping to identify magnesium deficiency, which can lead to irritability, muscle and nerve issues, as well as heart and kidney damage. On the flip side, too much magnesium can depress the central nervous system, leading to muscle weakness, and in severe cases, respiratory and cardiac arrest.
