- orionsbelt 3mo agoThey have blood tests for both (serum or RBC): The Magnesium RBC Test measures magnesium inside red blood cells, providing a more accurate assessment of magnesium status than serum tests.

- petilon 3mo agoThey only have blood tests, and that's not very useful.
- m_mueller 3mo agowouldn't a cell deficiency lead to it depleting also the magnesium levels in the blood, simply based on osmosis?
- stouset 3mo agoIf blood concentrations drop, you die.
- manoDev 3mo agoThe organism dumps Mg on the blood as much as necessary because it needs to remain in stable concentrations. When a serum Mg test comes out low, the patient already has severe deficiency and visible symptoms, so isn’t very useful unless you’re investigating a systemic issue. As explained by my endocrinologist.
