My TSH level is 0.06 mIu, normal range 0.46-4.98 mIU/mL ... Thyroid Antibodies level <1.0 IU/ML, normal range 0.0-0.9 (Under result notes: it says Low Positive) but my T3 and free T4 are both normal...T3 (Total Tridothyronine) level 1.7 ng/mL, normal range 0.8-2.0 ng/mL and my T4 Free (Thyroxine Free) 1.2 NG/DL, (normal range 0.7-1.8).
My question is two part, any thoughts on this would greatly be appreciated.
1) Do you think my test results indicates hyperthyroidism?
2) Is the I-123 scan the "best" next step and is there a less costly test (my insurance covers only 80%) that would provide my doctor the same information as the I-123 scan?
Thanks for your time,
