If all Micronutrient test RBC results are low or borderline low (iron, folate, magnesium, and fatty acids), and if serum values of these micronutrients are more robust in comparison, then anemia should be ruled out. Considering further workup by ordering an anemia panel. If many WBC values are also similarly low in comparison to serum, then micronutrients are possibly not being transported across the cell membrane due to impaired cellular permeability and fatty acid oxidation.
Will anemia influence Micronutrient RBC test results?
