High rt3 ?

[Meavis]

Hello,

Tsh. 4

Ft4 is 17. 12-22 Pmol/l

Ft3. Is 4.1. 3.1-6.8. Pmol/l

My rt3. 21.50 ng/dl

Vit. D. 90. Nmol/l

Ferritin. 74. 10-200. Ug/l

Zinc. 14. 9.2-18.4. Umol/l

B12. 650. 145-570. Pmol/l

Folaat. 20. 5-35. Nmol/l

Selenium. 145. 0.63-1.52 Umol/l

Hi my rt3 is to high and i use 50 mcg synthroid. I am suplementing iron it was low so i don t know if it will help. What can i do to lower rt3. I only use 50 mcg and i am under medicated.

I want to switch ndt but will this not keep my rt3 high? Because it still contain t4 I don t think my ft4 is that high but I have rt3 any way. Any help??

I doubt your high rT3 has anything to do with your dose of levo, because your FT4 isn't high enough. It could possibly be due to your low ferritin, though. In which case, changing to NDT won't have any effect on your rT3. You'll just have to wait and see if raising your ferritin brings your rT3 down. But, I wouldn't worry about it.

Hi greygoose,

Thanks for your answer.

I hope that is the issue but I am afraid that my ferritin 74 is already high enough. Do you think that if i get it raising to 90 then the rt3 would lower? Or is it good now.

I have a question about conversion range hoping you can help with the math.

In my country we use:

0.22-0.54. Nmol/l. My was 0.33

So that is: 14.33- 35.16 ng/dl. 21.48 rt3

So I have to be 2 point above but its a different range you use. You have like 10_24 ng/dl. That would mean if I calculate that 12 is a good level, 2 points above it's 14%.

14% of my range is 0.26 nmol/l

14% of the other ng/dl is like 17.23 ng/dl

That would mean I am just a little high. Because it looks high 21 but you use other ranges and I am 14 in yours? I hope you can understand me. It difficult to explain. I hope compared it good? I use the end rt3 conversion model but I have difficulty with the 2 point above bottom comparing?? That could mean switching to ndt completely would help me?

Hi this is the range, and i did a conversion to ng/dl i hope i did it right? Is it high?

0.22-0.54. Nmol/l. My was 0.33

So that is: 14.33- 35.16 ng/dl. 21.48 rt3

It depends on your range if it s high.
