Do my thyroid lab results indicate something is wrong?

I have a lot of hypo symptoms, so I went to an endo who ran a bunch of lab tests. The results (with range in parens):

TSH 0.791 (0.450 ??? 4.500)

Total T4 12.4 (4.5 ??? 12.0) High

T3 Uptake 21 (24 ??? 39) Low

Free Thyroxine Index 2.6 (1.2 ??? 4.9)

Free T4 1.19 (0.82 ??? 1.77)

Total T3 208 (71 ??? 180) High

Free T3 3.3 (2.0 ??? 4.4)

Everyone says Free T3, Free T4 and TSH are most indicative of thyroid problems, but mine are all normal. Other sources say that a low T3 Uptake is to be expected with high Total T4 (which I have), but don???t clarify if that indicates anything? I can find a lot of sources that say T3 Uptake is inversely related to TBG (Thyroid Binding Globulin), so since my T3 Uptake is low, I can expect my TBG would be high, which can be caused by excess estrogen. I am on BCPs, so that could be possible, but my previous lab results (do not have a copy) showed all of my female hormones (estrogen included) to be normal. I???m working on getting a copy of those (they were taken a month before these results).

Then Chris Kresser confused me further in this post: http://chriskresser.com/5-thyroid-patterns-that-wont-show-up-on-standard-lab-tests

In #4 on his list he says that hypo symptoms could be caused by decreased TBG, which would show as high TT3 (I have), low T3 uptake (I have), and low TBG. But I thought T3 Uptake and TBG were inversely related?

At my next appt I???m going to request my TBG be tested (along with these tests again), plus Reverse T3 (for a complete picture).

In the meantime ??? can anyone add to this? Do these labs indicate anything could be wrong, whatsoever? Are there any other tests I should have done related to this?

If anyone wants background, I???ve been strictly paleo for about 5 months now, no grains, no dairy, no legumes. Lots of meat, veggies and good fat. I have a whole host of problems I???m trying to figure out, and started with the hormone route as it could potentially clear a lot of them up.

Thanks!
