Hi everyone, newbie here.
Been reading a lot of other posts, learned enough to know that normal ranges aren't the same as optimal, and that a number of important markers that were not included in my test. I'm hoping I could get some advice as to my readings, and whether or not I should pursue further testing.
I'm finding myself very tired regardless of sleep or exercise. I'm female, almost 30, 5'2, 110lb and stable in weight. At first I thought it might be a B12 deficiency, since I had a series of mouth ulcers that lasted about a month in total. I also get lightheaded periodically. My mom had Graves, but these readings seem to suggest I lean towards the opposite.
Here are my readings of interest and reference ranges:
TSH: 3.88 mIU/L [0.27–4.2]
Free Thyroxine: 15.8 pmol/L [12–22]
Plasma Vitamin B12: 498 pg/mL [197–771]
Serum folate: 11.3 ng/mL [2.9–26.8]
Serum iron: 30.9 umol/L [6.6-26]
T.I.B.C 52 umol/L [41–77]
Ferritin: not measured
Thank you so much for your help!
[Edit] I should mention these were taken in the morning, but I was not told to fast, so had breakfast about an hour before the test.
