I've been having hypo and some hyper symptoms for a while now but more recently the worse symptoms (fatigue and brain fog) have increased. My own GP was positive that I was Hyperthyroid last month but my TSH came back as only 0.68 (0.35-4.5) so no further tests were carried out.
I'm at the end of my tether with feeling like this so I ordered a home blood test from Blue Horizon Medicals. The doctor from the lab reported them all normal but, surely, if my TSH is on the lower end my FT3 and FT4 should be higher?
TSH 0.49 (0.27-4.2)
FT4 14.5 (12.0-22.0)
FT3 4.1 (3.1-6.8)
TT4 95 (59-154)
Thyroglobulin Antibodies 16.3 NEGATIVE (0-115)
Thyroid Peroxidase Antibodies 12.0 (0-34)
Can anybody shed some light on what's going on with me? Am I looking for the wrong things? And, could this be a pituitary or adrenal problem?
Thanks in advance
