Latest Labs

Hello my friends,

It has been quite some time since my last post. I have been feeling better, although not perfect by any means. I still have some lingering symptoms; Internal tremors, ringing in the ears, lightheaded, and gaining weight (belly fat), even though I eat well.

Here are my latest labs: (Fasting am)

Tsh: 0.791 (0.450-4.500uIU/mL)

T3 Uptake: 29 (24-39)

Free Thyroxine: 2.2 (1.2-4.9)

Thyroxine (T4): 7.5 (4.5-12.0ug/dL)

Triiodothyronine (T3): 113 (71-180ng/dL)

Folate (Folic Acid): >20.0 (>3.0)

Vitamin B12: 629 (211-946pg/mL)

Hemoglobin A1c: 5.8 (4.8-5.6) Was 5.6 3 months ago

Insulin: 16.8 (2.6-24.9)

Ferritin, Serum: 78 (30-400ng/mL)

Ldl Cholesterol: 161 (0-99mg/dL) High

As always, your feedback is much appreciated. FT3 was ordered, not sure what happened.

I think you need more medication. FT3 and FT4 are both low in the range. We aim to get them in the top third or even the top quarter.

I agree with that

I am not on any meds, only taking supplements. I will look into it, but I'm pretty sure my doc won't prescribe anything.

Good to see you DanteNXS, I've never seen this T3 uptake before, what is it?

Don't get misled by the name!

Thyroid hormone uptake

Thyroid hormone uptake (Tuptake or T3 uptake) is a measure of the unbound thyroxine binding globulins in the blood, that is, the TBG that is unsaturated with thyroid hormone.[2] Unsaturated TBG increases with decreased levels of thyroid hormones. It is not directly related to triiodothyronine, despite the name T3 uptake.[2]

Thanks Helvella!
