Thyroid Test Results in -- Post T3/T4 cycle

[Peyomp]

This test was taken two weeks after a 6 weeks cycle of T4 and T3, that peaked at 50mcg T3 and 200mcg T4 (supposed to be equivalent to 100mcg T3), and tapered slowly down to nothing over 3 weeks.

T3 Uptake: 34.4%
T4 Free: 1.0 NG/DL
TSH: 2.21 UIU/ML

T3 Uptake Normal Values: 23.0-40.0%. Looks like I'm okay here.
T4 Free Normal Values: 0.9-1.8 NG/DL. Barely normal here. Definately on the low end.
TSH Normal Values: 0.35-5.50. Near the middle on this too.

So it looks like the only thing I'm on the low side on is T4 Free... how important is this in comparison to the others? Doctor?

Is that 1.0 NG/DL T4 Free something to worry about?

Typical post-T3 test.

Free T4 is low.

Remember that 80% of the free circulating T3 comes
from T4-T3 conversion.

It'll rebound back in a while.
