This is all very new to me so I was hoping someone might be able to help me understand my results a little better as my GP seems reluctant to entertain the idea that there might be something wrong with my thyroid due to normal TSH.
Quick background: I have constantly low energy (going up the stairs requires way too much effort for a 21 year old), I'm always tired and weak, constipated, dry skin and very depressed. I am also, however, underweight and struggle to put weight on. I went to the doctor's and had TSH and FT4 tested:
FT4 14.7 [12-22]
TSH 2.39 [0.3-4.2]
My B12, folate, ferritin are all in the middle of the reference range, Vit D right at the bottom of ref range. All my blood counts were way below ref.
Doctor said I was fine and evidently fit as a fiddle... Not happy with this I went and got myself tested with Genova labs:
T4 - 72 [58-161]
TSH - 1.55 [0.4-4]
FT4 - 12.7 [11.5-22.7]
FT3 - 3 [2.8-6.5]
RT3 - 0.29 [0.14-0.54]
Thyroglobulin <20 [<40]
TPO - <10 [<35]
So, the good, the bad and the ugly? My interpretation of this would be hypo (is being underweight ever seen?) I'm a little confused as to why my FT4, T4 and FT3 would be low but my TSH is normal.
Many thanks and all the best,
