Why should we have bloods 24 hours after levo dose?
Showed TSH 0.1 (0.2-6) and
T4
18.6 ( 10-20 ) I had teh
test
24 hours ( 8.30am) after last dose levo. So, should I be reducing my Levo dose? Last NHS
test
October 2023 showed same TSH and
T4
18.9. This was taken 12 hours after last levo dose.

Advice please
Please could I receive advice on these latest MMH private
test
results. I increased
T4
to 100 mcg from 75/100 ten weeks ago due to low T4 (for me but within range) now T4 abnormal. Palpitations were the main reason to increase and these subsided once I did.

t3 blood test at gp
hi my gp practice has been kindly filling my medichecks container for t3
test
when I get my tsh/
t4
nhs
test
done. However now they’ve decided it’s not possible to do private tests. Has anyone taken their gp on over this.

Latest
test
results are
T4
17.3 (range 11-21.2) and TSH 2.43 (range 0.27-4.2). These numbers seem much more in line with similar numbers this time last year and I’m having all the same symptoms. Last year my dose was increased. Does it sound like that needs to happen again? Thanks!

T4 not routinely tested
Hi, I am arranging post-hemithyroidectomy blood tests with the GP, and have been told that the lab will only
test
T4
if TSH reading indicates that it is necessary; wanted to check whether this means that they might miss something. I already know that I have Hashimotos. Thanks for any insight.

I managed to persuade my GP that I have symptoms of hashimotos and to humour me a TSH
test
,
T4
/T3 and anti TPO blood
test
was done.

T3 looks low to me! I have a goitre....help please.
I had to push for T3/
T4
blood
test
after gp took TSH and was then fixated on high cholesterol levels. I did some research and found that cholesterol levels were raised with thyroid problems and said I would not take Statins until thyroid sorted out.

tsh or t4 to determine over medication
It’s controversial in the United States between using tsh or
t4
to detect over medication. Which is the best
test
to conclude over medication tsh or
t4
? Any help would be appreciated.

My sis newly diagnosed and prescribed 75 mcg Levo but GP refuses to test free T4 or antibodies.
GP refuses to
test
for free
T4
or antibodies. I don’t think she should take the tablets until she has a baseline free T4 tested and antibodies. What you think?

Thyroxine half life & dose changes
I am aware of the waiting 6-8 weeks after a dose change etc before testing levels. I was wondering if anyone knows of a graph or paper that discusses the expected hormone concentration level from expected synthetic FT4 decline versus the increased thyroid hormone production after a dose decrease?

Splitting my T4 dose (amazing results)
Hi all I haven't been here for many years. Doing well generally. Thought I would share a simple thing I tried a good while ago now, but it has made a huge difference to my health. I simply split my T4 dose into 2 portions per 24h. I do 75mcg at bedtime and then 50mcg approx 12h's later. So

weird results
I have have been diagnosed with an under-active thyroid for about 20 years. As an ex-nurse it is my understanding that if it is broken it isn’t going to start working again! But my last blood results came back showing FREE T4 @ 52.8 normal-7.9 -16 serum THS 1.8 ( 0.3 -5.0) On 27/03/24 the results

NHS app
Hi all, I hope everyone has had a good weekend. I’m wondering if anybody knows if what appears as a consultation on the NHS app matches what is written on the system the GP’s use? To give some background I had an appointment about a mole like mark on my leg. GP sent me away with steroid cream as

Eating after Levo/t3
My most recent
test
shows my
t4
was just over normal, so I’ve been advised to cut it back very slightly from 112.5mcg per day to alternating from 100mcg one day and 112.5mcg the next. That was 2.5 weeks ago. Thanks

Secondary Hypothyroidism
Hi all, I had tests on my thyroid last year which showed my T4 as slightly low on 3 different tests. My GP told me there wasn't anything to worry, nothing to follow up. Fast forward to now when my GP has referred me to a specialist for something else and listed in my medical history 'Secondary Hypothyroidism
