red blood cell magnesium test
This test measures the amount of the mineral magnesium inside the red blood cells. This is the test I do most often, partly because I see many patients with fatigue, it is a very common deficiency and partly because it is a very difficult mineral to correct.NSTRUCTIONS. To complete the test: have the blood taken and put in the blood tube (see blood letting information), make sure that your name and date of birth are clearly marked on the tube. Check that your details are correct on the request form.
