39) To comprehensively evaluate magnesium status, both an RBC (Red Blood Cell) magnesium test
and a clinical assessment are necessary, especially if long-term prescription therapy is required.
Only an RBC (red blood cell) magnesium test
which is an expensive blood test that's not routinely performed--accurately measures magnesium levels.
Therefore, it is virtually impossible to make an accurate assessment of the level of magnesium in various body tissue cells using a routine serum magnesium test.
Unfortunately, most magnesium evaluations done in hospitals and in laboratories use the antiquated serum magnesium test.
overall] was considerably higher for the Abbott ARCHITECT magnesium test than for the others (r = 0.
The results of this study reveal that the magnesium test for the Abbott ARCHITECT system requires improved quality and restandardization; the results also reiterate an urgent need for standardization of albumin tests (5).
Example: We had been running only about one magnesium test
a week, yet the reagent became outdated and had to be discarded after two weeks.
3) A red blood cell (RBC) magnesium test
would be a better test to determine magnesium deficiency, compared to serum magnesium.
But not only is the RBC magnesium test
expensive, not a lot of labs perform it.
A new method for finding the correct amount of intracellular magnesium is an important recent research development because serum magnesium tests
aren't accurate enough.
Soluble and leachable calcium and magnesium tests
, the apparatus for which is shown in Fig.
These tests included monthly ferritin tests, magnesium tests
, calcium tests and potassium tests.
