Magnesium Blood Test

Magnesium Blood Test is a blood test that measure the amount of magnesium in your blood. It’s needed for healthy bones, heart, muscles, and nerves. Serum that is non-hemolyzed and heparinized plasma can be used to detect magnesium. Since the concentration of Mg2+ is 10 times higher in red blood cells than in ECF, this is why To ensure that hemolysis does not occur within the sample, the cells should be separated from the serum as soon as possible. Urine sample can also be used to determine Magnesium Mg2+ and 24 hours sample is more preferred.

Because magnesium is found in high amounts in all natural foods. Therefore, it is not deficient in the body. The more magnesium goes into the body, the more magnesium will be absorbed. Not only magnesium but also calcium will be absorbed.

On the other hand, phosphorus suppresses the absorption of both magnesium and calcium. Magnesium is actually needed to make ATP, Mg++ 95% is filtered from the renal glomerulus and reabsorbed by the tubules.
