I am posting my latest set of blood results in a table that also shows the history of blood tests that I have in relation to my hypothyroidism. I am slightly concerned that although I asked for a full blood test, the GP didn't test for Folate Serum, Free T3, Thyroglobulin Antibodies, or Thyroid Peroxidase Antibodies.
Should the missing tests be requested by me as a matter of routine?
Is anyone able to comment on my latest results and offer any advice?
I have chronic insomnia, am gaining weight in spite of exercising regularly and eating sensibly. I feel like I am in a rut and getting no support from my GP. I asked for a referral to an endocrinologist, but was told that my bloods are normal and there is no need for a referral.
Any advice would be appreciated.
Thank you

Free T4 (fT4) 17.4 pmol/L (11.5 - 22.7)
Ft4 only 52.7% through range
Request next dose increase in Levo to 150mcg daily
Approx how much do you weigh in kilo: 91 kg
Guidelines on eventual daily dose is approximately 1.6mcg Levo per kilo per day: Which would indicate a dose of 145mcg (in line with your recommendation to ask for an increase to 150mcg per day)
Antibodies are only ever tested once on NHS: Noted
Exactly what vitamin supplements are you taking: High strength Vitamin D
Serum B12 is far too low if under 500: Didn't realise that was low. I will look at your recommendations for a B12 daily supplement.
With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a separate B12 supplement
A week later add a separate vitamin B Complex
Then once your serum B12 is over 500 (or Active B12 level has reached 70), you may be able to reduce then stop the B12 and just carry on with the B Complex.
If Vegetarian or vegan likely to need ongoing separate B12 few times a week
Igennus B complex popular option. Nice small tablets. Most people only find they need one per day. But a few people find it’s not high enough dose and may need 2 per day and/or may need separate methyl folate couple times a week
Thorne Basic B recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule) Thorne can be difficult to find at reasonable price, should be around £20-£25. iherb.com often have in stock. Or try ebay
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 5-6 days before ALL BLOOD TESTS , as biotin can falsely affect test results
In week before blood test, when you stop vitamin B complex, consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg) and continue separate B12 if last test result serum B12 was below 500 or active B12 (private test) under 70
