Blood Test Results

I have my blood test results. Because I took my full dose of T3 around 24 hours before the test, it’s probably not that accurate. Slow Dragon mentioned it could be up to 20% lower than it actually is. If it is the full 20%, it takes the T3 up to 7.08.

I feel as though something isn’t right.

My T4 seems fine so I suspect the problem could be the T3. I think I’ll reduce the T3 by one quarter

I’m possibly about to switch brands for T3. Would I have to wait to reduce or could I reduce at the same time?

How do people ever find their ‘sweet spot’?

How much levothyroxine are you currently taking

How much T3

What about vitamin D, folate, ferritin and B12 levels

T4 - 100mcg

T3 - 18.75mcg

I haven’t had vits checked, but I supplement B12, D and multi B. It’s the ones recommended on here.

Thank you!

yes suggest you reduce T3 by 1/4 tablet and retest in 8-10 weeks

When was ferritin and iron levels last tested

Thank you very much!

I will reduce by ¼ - I’m guessing I can’t do that at the same time as a brand change?

My last blood test for ferritin and iron was 1 Feb 22. I’d do them privately but I can never get enough blood. The last time I did it, I drank the whole day the day before, and followed all the instructions but nothing came except a couple of drops. They sent me another test because there wasn’t enough blood. I can ask my GP to do it again if you think it’s necessary.

Thank you again.
