Recent bloods for my daughter

[Refat]

Hi all, please could i get some advise on my daughters recent results. She started off on levo 25 mcg in july and after 6 weeks her blood test came back as T4 13.8 (11 - 22.6) T3 5.5 (4.2 - 7.4) tsh 3.1 ( 0.2 - 4.0). She had an increase of levo to 50 mcg same brand which is mercury pharma. She had her bloot test 3 months after being on 50 mcg and results are T4 16 and tsh being 0.75. Doctor refused to test t3. Im quite puzzled at why her 0.75 has gone so low yet t4 is now mid range only. Is this normal, please help.

Each person has their own interwoven ideal amounts of TSH, T4 and T3 in health. When on T4 things are different. The TSH is simply responding slowly to a higher T4 dose. 25ug is not the right way to start therapy if your daughter is less than 60 years of age. It should have been 50 ug straightaway. The answer is that your daughter is responding increasingly well to T4 and gradually building up to proper therapeutic levels. Normalising TSH is not an instant event; it can take months or years. And TSH by itself is not a particularly useful marker in optimising therapy.

Thank you for your response.

I was diagnosed age 44 with Myxoedema (Hashimoto's total thyroid failure and it would never be able to recover). My surprised Dr said I had to start on a very low 25mcg dose, to avoid shock to my system. He increased it gradually over months and I've been on 150mcg for years (but still feel tired, aching and gaining weight!). Some people with only partial loss may have up and and down levels as their hormones try to work.

Looking at previous posts she’s only 10?

Important to regularly retest her vitamin D, folate, ferritin and B12 levels

Have you seen children specialist thyroid endocrinologist?

Hi SlowDragon. Yes we are with a child endo. We are due a telephone consultation after 4 months on 28th Jan. They were not willing to test ferritin, vit D or B12 and folate as they said it was within range just less than a year ago. I am giving her supplements though, not too much but just enough and nothing too extra.
