Hi, I'm trying to gather as much info as I can to take to see this endo next week. My rheumatologist tested my folate, ferritin and B12 a month ago and said the levels were fine. I have asked for a copy of the results to take with me, along with the Blue Horizon thyroid profile. These are the levels that came through the post today...
Ferritin 31.0 ug/L ( 5-148)
B12 388 pg/ml (191-946)
Folate 5.5 ng/ml. (4.6-18.7)
Any advice on these gratefully received xx
Back to school for the doc I am afraid ! Your Ferritin - Stored Iron - needs to be around 80/90. B12 at the TOP of the range. Folate too. The result of your B12 is unreliable anyway as it is both bound and unbound B12. Only about 20% of that result reaches the cells where it is needed. hence why it needs to be high in the range.... With your stored iron being low - the cupboard is depleted - so not much to draw on.
Absorption issues ? Are you supplementing ? Thyroid results ?

Am not an expert - have just learnt from others on this forum who have such good knowledge....
What about VitD - was that tested ? Hope all goes well with the Endocrinologist next week.
She didn't bother to test my vit D as I am already chronically deficient in that and supplement, just said keep supplementing. I have secondary hyperparathyroidism. Not yet on any meds as TSH also 'normal' 3.33 (0.5-4.2) but blue horizon tests showed I'm not making anywhere near enough T4 (under range) and T3 low in range. Thanks for your response x
Hope your Endo thinks outside the box and doesn't just go with the TSH.
