Experiences with

T4 test

Hello all, I am on 150mg thyroxine daily, I did bloods yesterday, took meds 4 hours before the test, T4 came back 33mmol. I am super anxious if its dangerously high, do i need to go to hospital? How do i dose now? :( Thankful for any advice!

My GP did a TSH/T4 test but said it was 'in range'..... Any advice gratefully received. Thanks

I cold water swim which helps fibromyalgia . 3 months ago following routine TSH and free T4 test was told my TSH was too low think it was 0.2 I have never asked about if T3 is checked and have had never asked about other tests .

TSH...3.35 Another test not performed so this result is from Feb 22 No T3 or T4 test done!

Tsh is 2.3 range 0.27to 4.2 T4 22.9 range 12to 22 Test taken at 8am no levo 24 hours prior to test

On the plus side, I did my private TSH, T3 and T4 test today so hopefully those results might give an incline in to how things are doing, but even if they come back out of range I really don't believe my GP will act on it without the green light from the consultants.

This is my first blood test on a T4/T3 combo. I’ve read through some previous posts on this and just want to check I have it right. I take 50mcg T4 and 10mcg T3 split into two doses normally. I take T4 and 5mcg T3 on waking and 5mcg T3 a few hours afterwards. Blood test is booked for 8.40am.

Saw GP - he refused to up my meds - said risk of stroke - sent me away with sick note for depression n anxiety 🤬😭 However did agree to T4 / and antibodies test Any tips for how to actually cope with work - I’m going back Mon - can’t have more time off - risk of losing my job / mind you probs just

I know we have said T3 is the key result that they don't test. Thats why I have bought a T3 T4 TSH test. Will be interesting what the hospital says with the other results Wednesday. With going onto 100mcg I have noticed very slightly the off balance feeling is still there but isn't as noticeable.

I didn’t take my morning dose of Levo…(.must have had a premonition that they might do it,) but I had breakfast, … how will this affect my results , , they test T4 and TSH only. Thank you for any response.

I take all my thyroid meds at 7.30am every morning; that’s 125mg levothyroxine and 50mcg t3 (I find it suits me better than splitting the dose). What should I do before a blood test? TIA

Am waiting for emailed copy of test results, the only result given over phone was T4 which was 16 ?

I am hypo based on TSH but Not hypo based on free t4&t3 ... Latest blood test results : TSH : 13 ( 0.5 - 4) Free t4 : 17 ( 10 -20) Free t3 : 5.1 ( 3.5 - 6) Please advise Thanks

Followed advice on here early test no T4 for 24 hours bef. I currently take 100mcg/125mcg levothyroxine alternate days, I stick to ACCORD brand.

I’m due a blood test tomorrow (they will only test tsh & t4). I’ve spend the past two months arguing with my gp saying I want to stay on my current dosage as I feel great been on it nearly a year but my last test tsh was 0.01 under range and t4 50%, she’s insisting I’m over medicated.

This is as a result of my Levo reduction from 150 mcg to 125 mcg: TSH 2.4 Free T4 18.7 The blood test was done first thing in the morning and 24 hrs after taking my last Levo. Thank you.

I have had an under active thyroid for over 20 years ,I take Thyroxine 100 ,recent blood tests showed my T4 as 30 and has increased my meds to 125 then another blood test in June , I have been having problems sleeping ,being cold extremely dry skin/&hair etc all the usual signs , normal readings for

In Sept 21 I reduced my T3 from 17mcg a day to 15mcg a day (100mcg x T4 stayed same) and these are my latest test results - see attachment. At 7am I took my daily 100mcg x T4 together with 10mcg x T3. At 3.30pm - my blood test was done. I was thinking my T4 looks low - which seems curious.

Im happy to go private, as the NHS refuse to test for my T3, T4 and having met an endo under the NHS before, it was not useful at all for me. Any help will be greatly appreciated

I don't know what my test mean. TSH 1.48. T4 0.9. Can anyone answer this for me.
