I am trying to get to the bottom of feeling so bad, all the symptoms of being hypothyroid but blood test levels all normal. However just had vitamins B12 vit D etc done and only one to come back out of range is serum folate which is;
serum folate 24.3 (4.6 - 18.7)
Please are there any thoughts on this? Have no idea what it means or what it indicates.
