I had my vitamin D and a full iron panel taken in November 2017. They were a private draw. The results were:
Vitamin D - 25-Hydroxyvitamin D Total = 113. Ref. range 100-200
Iron - 13.6 umol/L (6.6 - 26.0)
TIBC - 67 umol/L (41 -77)
Transferrin Saturation Percentage - 20 (20-55)
Ferritin - 49 ug/L (13-150)
I decided I needed to supplement and try to get levels up a bit. I took Solgar Gentle Iron for about 3.5 months and then retested. This time the GP did it and of course the references are completely different and I'm not sure how to compare them. They don't look much different to me, but I hope someone with more experience can comment.
New results from April 2018
Vitamin D - 115 nmol/L (Just says; Greater than 50 = Vitamin D sufficiency)
Serum Iron - 13.3 micromol/L (11 - 30)
Serum transferrin - 2.87 g/L (1.8-3.6)
Transferrin Saturation Index - 21 (16-50)
Serum Ferritin - 32.9 microg/L (10-200)
At the same time I've had my thyroid results back. I'm stuck on 50mcg Levo.
Even though I asked for them, they have not tested my antibodies!
TSH - 10.30 (0.27 - 4.2)
Free T4 - 16.9 (12.0 - 22.0)
Free T3 - 4.4 (3.1 - 6.8)
My TSH was around 4.5 last summer when I began Levo. Nice to see I'm steadily getting worse. That will be why my hair is nearly gone on top!
With these reference ranges, where should my Free T's sit to be approaching optimal? I know they should be in the upper end of the range, but I'm not sure where, in number terms, that should be.
Thanks for any help you can give. My vitamin B12 was tested privately last autumn with an active test and came back with good results.
