I have no idea, I'm left guessing because magnesium is not part of the regular suite of lab panels. You're doctor would have to request an additional electrolyte panel. Even then, a persons complete magnesium status is hard too tell because most of it is stored inside bones and cells, the lab test only measures serum levels.

I just presume my magnesium intake is low and supplement accordingly. I'm a 34 year old caucasian male, and using the tables below, my median dietary intake of magnesium is 326 mg/day. Referring to the Recommended Dietary Allowances (RDA) table, the RDA for my age group is 420 mg/day. Subtracting 420 from 326 leaves me with a daily deficit of 96 mg/day. Thus I take 1000 mg of magnesium glycinate (100 mg elemental magnesium) every day, in addition to the 50 mg of elemental magnesium supplied in my multivitamin.

Median dietary intake of magnesium[1]:
326 mg/d (mean 352 mg/d) among Caucasian men
237 mg/d (mean 278 mg/d) among African American men
297 mg/d (mean 330 mg/d) among Mexican American men
237 mg/d (mean 256 mg/d) among Caucasian women
177 mg/d (mean 202 mg/d) among African American women
221 mg/d (mean 242 mg/d) among Mexican American women
