RBC Magnesium test (not Serum)

[destiny234]

I am trying to find a home blood test for RBC Magnesium (as the serum test is inaccurate due to most of the magnesium being in your muscles and bones). I have read that too little magnesium may be connected to Afib. Does anyone know of a company in the UK that does this RBC Magnesium test? All the usual companies just do the serum test. And has anyone got any knowledge of the connection between low magnesium and Afib, ie levels?

I have just had mine done by the The Doctors Laboratory, London. Much more expensive than the previous lab, which had stopped trading but postage package very efficient and results sheet good.

My London Naturopath prescribed for me at the outset a Mg compound partnered with Co Q10 and said both should be in the upper quartile. I suggest you get them tested first and every 6 months.
