After showing my test results from Medicare last year to my GP and he upped my Levothyroxine to 75 and 100 on alternate days. I did a Medicare test in February this year and readings have changed as follows:-
TSH 5.6 (down from 11)
Free T3 (up from 2.8)
Free Thyroxine 22.1 (up from 18.1)
I still feel exhausted and fall asleep during the day despite falling asleep as soon as my head hits the pillow and generally I get 7 to 8 hours solid sleep at night.
Can you please add the ranges for your test results (as these can vary between laboratories) Nowebag49.
When was the last time you tested key thyroid vitamins (ferritin, folate, B12 and vit D)?
The tests were with the same laboratory and ranges as follows:-
TSH (0.27 - 4.2) Free T3 (3.1 - 6.8) Free Thyroxine (12 - 22)
Results
2024 Test 11 2.8 18.1
2025 Test 5.6 3.2 12.1
I was prescribed Ferrous fumarate 210mg in February 2022
Accrete D3 tables July 2020
please add Ft3 result
when you did your test was test early morning and last dose levothyroxine 24 hours before test
Do you remember if last dose was 75mcg or 100mcg
Which brand of levothyroxine are you taking
Do you always get same brand at each prescription
Exactly what vitamin supplements are you taking
Next step is to test vitamin D, folate, ferritin and B12
2024 Test 11 2.8 18.1
2025 Test 5.6 3.2 12.1
TSH 5.6 (down from 11)
Free T3 (up from 2.8)
Free Thyroxine 22.1 (up from 18.1)
Can you double check
2025 test …..is Ft4 result 12.1 (12-22) or is it 22.1
Free thyroxine is 22.1
Was last dose levothyroxine 24 hours before the test ?

Serum ferritin level is the biochemical test, which most reliably correlates with relative total body iron stores. In all people, a serum ferritin level of less than 30 micrograms/L confirms the diagnosis of iron deficiency
Never supplement iron without doing full iron panel test for anaemia first and retest 3-4 times a year if self supplementing.
aiming to maintain Ferritin at least over 70
It’s possible to have low ferritin but high iron
Test early morning, only water to drink between waking and test. Avoid high iron rich dinner night before test
If taking any iron supplements stop 3-5 days before testing
Aiming to maintain serum B12 over 500
Active B12 over 70
Folate at top of range
25ug of vitamin D is quite likely too little
Test twice yearly when supplementing
Can test via NHS private testing service
Aiming for vitamin D at least over 80nmol
Low vitamin D
GP will often only prescribe to bring vitamin D levels to 50nmol.
Some areas will prescribe to bring levels to 75nmol or even 80nmol
leedsformulary.nhs.uk/docs/...
GP should advise on self supplementing if over 50nmol, but under 75nmol (but they rarely do)
mm.wirral.nhs.uk/document_u...
But, improving to around 80nmol or 100nmol by self supplementing may be better

Once you Improve level, very likely you will need on going maintenance dose to keep it there.
