Can someone help me de-code the meaning or implication of these test results please?
T3 Uptake = 38 High
The rest are normal according to lab report:
T4 (thyroxine) = 5.4
Free Thyroxine Index= 2.1
TSH = 3.23
T4, Free = 1.3
I don't take estrogen or birth control pills. I don't understand why my T3 uptake is high when the rest of the thyroid tests are normal.
Thanks for any help or ideas. : )
