Please could someone give me a full list of the tests I need for my under active thyroid? I have just had my blood results back and to my frustration they didn’t test B12 even though I was told they would!
My TSH is 0.05 ( range 0.27-4.2)
T4 11.4 (range 12-22)
T33.6 (range 3.1-6.8)
Folate 4 (range 3-22)
Vit D 92(range 50-150)
I take 75mv levothyroxine
and 2x5mc liothyronine one in the morning and one in the evening
I feel under medicated and have put a stone on since my liothyronine was cut from 3x15mc each day (yes big drop!)
I run every day 5 miles and eat one meal low cal no carbs every day and I’m becoming very fed up and a bit angry because my ‘tired fed up fat self’ is not a good version of me!
Thank you for any help xx

For full Thyroid evaluation you need TSH, FT4 and FT3
EXTREMELY important to test ferritin and B12
Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .
Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
If/when also on T3, make sure to take last 5mcg of daily dose 8-12 hours prior to test, even if this means adjusting time or splitting of dose day before test
Is this how you do your tests?
Thriva also offer just vitamin testing
Assuming test was done as recommended, your results show you are under medicated
Both Ft4 and Ft3 are too low
Probably first step is to increase levothyroxine by 25mcg and retest in 6-8 weeks
This should increase both Ft4 and Ft3
Which brand of levothyroxine are you currently taking?
Folate is low
Ask GP to text B12 and ferritin or test privately
Once B12 been tested
supplementing a good quality daily vitamin B complex, one with folate in (not folic acid) may be beneficial.
This can help keep all B vitamins in balance and will help improve B12 levels too
Igennus Super B is good quality and cheap vitamin B complex. Contains folate. Full dose is two tablets per day. Many/most people may only need one tablet per day. Certainly only start on one per day (or even half tablet per day for first couple of weeks)
Or Thorne Basic B is another option that contain folate, but is large capsule
If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results
I have always ran and do it partly from habit ( I feel ‘wrong’ if I haven’t ran first thing -weird huh??😂 but also because it just makes me feel better in myself
My low carbs are because I hate my weight gain but before when my weight was fine, I ate the same as I do now
Many people find Levothyroxine brands are not interchangeable.
Many patients do NOT get on well with Teva brand of Levothyroxine. Teva contains mannitol as a filler, which seems to be possible cause of problems. Teva is the only brand that makes 75mcg tablet. So if avoiding Teva for 75mcg dose ask for 25mcg to add to 50mcg or just extra 50mcg tablets to cut in half
Teva, Aristo and Glenmark are the only lactose free tablets
Physicians should: 1) alert patients that preparations may be switched at the pharmacy; 2) encourage patients to ask to remain on the same preparation at every pharmacy refill; and 3) make sure patients understand the need to have their TSH retested and the potential for dosing readjusted every time their LT4 preparation is switched (18).
Levothyroxine is an extremely fussy hormone and should always be taken on an empty stomach and then nothing apart from water for at least an hour after
Many people take Levothyroxine soon after waking, but it may be more convenient and perhaps more effective taken at bedtime
If you normally take levothyroxine at bedtime/in night ...adjust timings as follows prior to blood test
If testing Monday morning, delay Saturday evening dose levothyroxine until Sunday morning. Delay Sunday evening dose levothyroxine until after blood test on Monday morning. Take Monday evening dose levothyroxine as per normal
No other medication or supplements at same as Levothyroxine, leave at least 2 hour gap.
Some like iron, calcium, magnesium, HRT, omeprazole or vitamin D should be four hours away
