As you're not sure which one may be the cause maybe stopping one for a few weeks might resolve the quandry. If there's no change, then add it back in whilst stopping the other for a few weeks.
Never ever accept an opinion...always get actual results and ranges
You are legally entitled to printed copies of your blood test results and ranges.
The best way to get access to current and historic blood test results is to register for online access to your medical record and blood test results
UK GP practices are supposed to offer everyone online access for blood test results. Ring and ask if this is available and apply to do so if possible, if it is you may need "enhanced access" to see blood results.
In reality many GP surgeries do not have blood test results online yet
Alternatively ring receptionist and request printed copies of results. Allow couple of days and then go and pick up.
Important to see exactly what has been tested and equally important what hasn’t been tested yet
For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also EXTREMELY important to test vitamin D, folate, ferritin and B12
Vitamins need to be at optimal levels ....not just bumping along bottom of range
Come back with new post once you get actual results
If you have started back on HRT ....get FULL Thyroid and vitamin testing (privately if necessary) 6-8 weeks later
Thousands of members only make progress when organising own FULL thyroid and vitamin testing
NHS testing is frequently completely inadequate
Essential to always get test done as early as possible in morning before eating or drinking anything other than water and last dose levothyroxine 24 hours before test
I always take my meds before test as i thought it important to know how high the thyroid hormones would be at there highest concentrations so i know im not doing my body harm by being overmedicated. I know they wear off but maybe we should alternate, say first blood draw after taking morning dose and the next blood draw not taking our medication until after blood draw to see how much or blood results change.
Leading Endocrinologists always recommend testing as we say ...
Levothyroxine is a storage hormone....it lasts 7-10 days in body. What you don’t want is to get false high Ft4 if testing after too soon after taking levothyroxine
Always tests as early as possible in morning before eating or drinking anything other than water and last dose levothyroxine 24 hours before test ....because you need to see lowest level
“According to the current TSH reference interval, hypothyroidism was not diagnosed in about 50% of the cases in the afternoon.”
“Further analysis demonstrated inadequate compensation of hypothyroidism, which was defined in 45.5% of the morning samples and in 9% of the afternoon samples”
TSH levels showed a statistically significant decline postprandially in comparison to fasting values. This may have clinical implications in the diagnosis and management of hypothyroidism, especially SCH.
When i discuss my results with my endocrinologist he knows i take my medications prior to being tested, i always do. I f they are different i tell him i missed a dose if i have, or if i have started to take HRT etc . I guess your TSH will tell regardless if you take in the morning or not it will only be FT3/FT4 that will be high but I'm sure they can tell who has and has not take before the test by results .
TSH takes at least 4-6 weeks to respond to dose changes
Ft3 is unaffected by when you take levothyroxine (and very rarely tested unfortunately)
A common scenario
Results - taking levothyroxine before blood test
TSH 0.98 (0.2-4.8)
FT4 20 (12-22) - 80% through range
Ft3 3.8 (3.1 - 6.8) 19% through range
Results taking levothyroxine 24 hours before blood test
TSH 0.98 (0.2-4.8)
FT4 15 (12-22) - 30% through range
Ft3 3.8 (3.1 - 6.8)
Clearly in both sets of results Ft3 is far too low and patient needs dose increase
But in first set of results GP likely to look at Ft4 near top of range and say “no room for increase”
In second set of results Ft4 shows there’s lots of room for dose increase
Dr Toft, past president of the British Thyroid Association and leading endocrinologist, states in Pulse Magazine,
"The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range - 0.2-0.5mU/l
In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l.
Most patients will feel well in that circumstance.
But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l.
This 'exogenous subclinical hyperthyroidism' is not dangerous as long as serum T3 is unequivocally normal – that is, serum total around T3 1.7nmol/l (reference range 1.0-2.2nmol/l)."
You can obtain a copy of the articles from Thyroid UK email print it and highlight question 6 to show your doctor
I thought it might look something like that, with taking levo and then without. My endo told me it takes weeks for TSH to change. I have just received my results with ranges so ill post them on here. My TSH is usually a lot lower but i started HRT and was on it for seven months. My TSH was in the 0s but now very high for me.

Should be removed now, thanks i thought admin would have done it before it posted. I did need a dose change by these results and i really did feel unwell thats why i did the test early as my GP did not check after 8 weeks of HRT. I agree i think I need to up T4 to 150mcg everyday rather than every other day.
My GP has not given me results with ranges, i have been onto them for a long time so not sure about VitD, folate, ferritin or B12. Im guessing Vit D still low or they would not still prescribe me D3. I will get onto them again, they do not respond to e mails and i do not use phones or own one so i will call in and knock the window and ask.
Admin do NOT see your posts before they appear on the site.
If you realise the name should not appear, and have been told it should not appear, why not remove it yourself? There are only very few admins, and we do not always see everything.
I thought i had removed it from the post, thank you and sorry to cause trouble. I will double check in future to make sure it has actually been removed. xx Please forgive .
Will only be reported as abnormal if below range ...but we need optimal vitamin levels (though NHS not obliged to treat to bring to good levels, that’s down to the individual)
Ferritin range typically 14-150
Optimal results need to be over 70
GP would only say Ferritin is too low and needs treatment with supplements if result under 14
This is interesting because I have noticed that many patients with Hashimoto’s disease and hypothyroidism, start to feel worse when their ferritin drops below 80 and usually there is hair loss when it drops below 50.
Vitamin D
GP will often only prescribe to bring levels to 50nmol.
Some CCG areas will prescribe to bring levels to 75nmol
I have been trying to get feedback and test results with ranges since my latest panic of fatigue, hair loss, burning scalp, acute constipation from either the GP or the Endo but you have to go through the secretaries and i think they ignore my constant e mails. I stopped my HRT as i thought it might be that that was making me ill and today i finally got my results and my TSH had gone up to 2 which is still in range but i can not get out of bed with TSH at 2 but they say no change so now I'm back on HRT and have been for a bout a week . I thought also maybe as i have been on T3 for a good while now i thought i may have been over medicating but now i know as i was about to stop T3 in case it was that being to high and causing hair loss which happened to my son who is hyperthyroid, he lost all his hair.
