Testing Magnesium Levels

Testing Magnesium Levels

While magnesium deficiency is very common, proper testing shows you the degree of your deficiency, which can help you avoid serious health conditions. Here we look at:

  1. Why standard serum blood tests are proven to be unreliable.
  2. The 4 alternative tests that are more accurate in spotting deficiency.

1. Standard serum blood test (most used, least reliable):

2. Exatest (most accurate, least accessible):

3. Ionized test (most accurate, least accessible):

4. RBC test (highly accurate, more accessible):

5. Magnesium loading test (relatively accurate, not practical):
