Confused By Thyroid Test Results

Hello,

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. : )

T3 Uptake is considered an obsolete test and of almost no value.  

Please post the reference ranges for your thyroid tests.  Ranges vary lab to lab and have to come from your own lab report.

Do you have symptoms?
