Magnesium, RBCALL3.6-7.53.6-7.5mg/dL

RBC magnesium...
RBC magnesium results reflect the intracellular stores and general homeostasis of magnesium. Results may be falsely low if RBCs in the submitted specimen are lysed or not promptly separated from plasma

RBC magnesium concentration is reported as milligrams per deciliter (mg/dL). To convert concentration to millimoles per liter (mmol/L), divide the result by 2.43

This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA-certified laboratory and is intended for clinical purposes
