Blood test interpretation - and the power of Brazil nuts

Following my recent post (https://healthunlocked.com/thyroiduk/posts/133551728/blood-test-help-please) where I was worried that my T3 had dropped, I had new blood results today. The last test, at the beginning of May, was

TSH 0.114 (0.40-4.00)

T3 4.270 (3.1-6.8)

T4 21.440 (12.0-22.0)

and I was beginning to be symptomatic again (complete story in previous post). My doctor had no clue, called the endo who said I should drop my dose from 125mcg to 100mcg and be tested in 3 months; the last time I was on 100mcg it only took 6 weeks for me to end up in hospital, so er, thanks but no thanks. Instead, I did some reading on here and did 4 things: I started eating 4 Brazil nuts a day for selenium, cut soya milk out, made sure I took my vits regularly (zinc, magnesium, D3 and a B complex) and made sure there was always at least an hour between taking my levo and my morning cup of tea, which I'd got a bit lax about.

Today my results (blood taken on 6 June, so a month after the previous ones) were much better, and I feel better:

TSH 0.051 (0.40-4.00)

T3 4.84 (3.1-6.8)

T4 23.04 (12.0-22.0)

I would like my T3 to be still higher (mid-range is 4.95) but this is much more in line with my results when I feel really well.

What do you think? Any comments appreciated!

Your blood test results suggest you might not be converting t4 to t3 very effectively. The selenium in brazil nuts helps with this. Have you considered adding a tiny bit of t3? It worked for me

I have thought about it, indeed, but I'm not sure if my results are bad enough for that, and also I have no idea whether my doctor would agree to it, especially after the endo giving such advice. It's good to know it worked for you - how much are you on?


Please, if you are anywhere near Gloucester, could I have the name and contact details of your GP and endocrinologist? Think this has to be in a private message.

I ask because my T3 is low but my GP will absolutely not consider treating or referring me.


I'm sorry, thyr01d, I live in Slovenia and have done since long before my diagnosis. I know I'm lucky that I always get all three results tested and usually my doctors listen to me (apart from the endo) - I've heard, also from a member of my family, that things are not nearly so good in the UK! Good luck with finding a new doctor. I can recommend a marvellous nutritionist in Stroud, as it happens - she has been helping me for about 20 years. Pm me if you want her details.


Ah RustyMary you are in Slovenia, well thank-you anyway for such a nice, warm and encouraging email.

Hi there thyr01d. I live in Worcestershire and have been treated with t3 by an endo at the Worcestershire hospital. Had to pretty much demand a referral from my doctor, but was lucky to be seen by a forsighted endo, when it comes to t3. Not so much help when it comes to vitamins and minerals, but I have been recently told that I should ask to be referred to a nutritionist for this....will do this on my next appointment, as I am feeling fairly well right now 😀 Would you like me to pm you details of the Worcs guy?
