Please could someone look at my latest blood test results after two months on T3

[Katkin1]

I am currently on 25mcg T3 and 100mcg T4. I've just had July test results back today:

TSH 0.01 (0.35-5.50)

T4 12.8 (10.50 - 20.00)

T3 4.7 (3.5 - 6.5)

In May the results (on 20mcg T3 and 125 T4) were:

TSH 0.01

T4 13.2

T3 4.8

Before T3 they were:

TSH 0.13

T4 20

T3 4.6

Please can someone help me understand these results? I feel better but still don't feel as well as I'd hoped taking T3 and to me the results show a decrease in TSH but not much change in T4 and T3 levels. Is anyone able to help me understand what this means please?

Your T3 probably hasn't gone up much because your body is actually using it, which is probably why you are starting to feel better. It looks like your T3 could be a little higher so you could probably do with a slight increase and then you might feel even better. You may find that more T3 and less T4 is the way to go. I read somewhere that it is best to take your T4 at a different time from your T3. That might help if you're not already doing that I'm not medically trained though. These are just suggestions that work for some people.

Don't forget to make sure your iron, ferritin, folate, B12 and vitamin D are all optimal. These will have an impact on how you respond to your thyroid meds.

I hope that helps a little.

Thanks for your help Carolyn. I will try to take my T4 at a different time to the T3. I hadn't thought about the fact that T3 was staying the same because I am using it. How can I tell if I need more T3 if the figures don't change please? What should an optimal T3 reading be? Do you have any information on taking T3 and T4 at different times to hand please?

Glad you mentioned B12. I keep forgetting to take it so will go and take it now. The others were optimal last time I had them tested back in March (I think) except for D3 which I supplement.

Best wishes

I think you have to go by how you feel. You really want your T3 a little higher (well most people would, but not everyone).

I'm afraid I don't have the information about taking T4 and T3 separately but it was something along the lines of, in some people, if you take them together the T4 gets converted into a higher proportion of reverse T3. If you take them separately this doesn't happen. Of course, not everyone has this problem. It might just be something worth trying if you think you might have a reverse T3 problem.

I take a T4/T3 combo and take my T4 last thing at night, T3 first thing in the morning and mid-afternoon. Carolyn, didn't think of the reverse T3 issue when taken together, interesting.
