magnesium deficiency - test?

[Guest guest]

I may need to transfer my primary care to a non-LL for convenience. I

have been getting IV magnesium about once a month. I dont know a thing

about it except that it ablates my muscle twitching immediately, which

is useful because I meditate.

I currently havent had an IV in a month, and am starting to twitch a

little, so maybe I could establish myself as magnesium-deficient by

getting an intracellular Mg assay of some kind done?

Anyone know how this works, whether a non-LL would have easy access to

the assay, and whether I would be likely to be clinically deficient by

non-LL standards? Or know any literature supporting Mg deficiency in

lyme or CFS? THanx
