My Neurologist had me do the NutrEval test where your urine is tested for vitamin and minerals, etc. My B12 has been as high as 1900 when doing a blood test at my regular doctor. The report came back for the NutrEval and it shows a B12 of 12. So obviously I’m not absorbing it, but is this number even possible? I have read many of Mrs. D’s posts and that is what prompted me to ask for more tests. I don’t see the Neurologist for another week. My question is first if this number is possible and secondly, if a person isn’t absorbing vitamin b12, will they absorb a supplement or do they need injections?
