TSH 2.54 (0.35-4.94) mIU/ML
SGOT 80H abnormal (11-47) IU/L
SGPT 110H abnormal (6-66) IU/L
Your TSH first of all is too high. Most people with NO thyroid problems have a TSH closer to or even below 1
Your FREE T4 is way too low also, no wonder you feel so bad, it should be about 1.25, this is your 70% target range or upper 1/3 of the labs range. Most people feel best when the FREE levels are in the upper 1/3 or 70% target range, below this is where the hypo symptoms are present.
The tests you really need for a good picture of thyroid function are...
Thyroid antibody testing TPO, Tg (these indicate Hashi's)
Just a little info.....
The FREE thyroid tests measure your actual thyroid hormones, these are the ones available for your body to use, FREE levels are NOT bound by proteins.
The TOTAL blood levels measure both bound and active hormone, this does not tell how much is active and how much your body has available to use, only a small portion of Total levels are actually free.
T3 Uptake has nothing to do with YOUR T3, its T3 from a test tube used to measure the binding proteins.
TSH is a pituitary response and often tells what it thinks your thyroid is doing, once on treatment the TSH can be pretty deceiving and the FREE levels need to be watched for treatment and the TSH needs to be suppressed.
The ranges are gauges, being "in range" does not mean all is well, with thryoid levels, the FREE levels need to be in the upper 1/3 of the range for women and about mid range for men.
So, when you get bloodwork, specify you want the FREE T3 and FREE T4, otherwise they may do totals.
