We really need ranges on these results (figures in brackets after each result).
Most people on levo need low TSH around 1-2 to be adequately treated. The FT4 needs to be in top third of range.
You also need FT4 & FT3 tested at same time, plus ideally TT4.
If they have not been done ......Suggest you ask GP to check levels of vitamin d, b12, folate and ferritin. These all need to at good (not just average) levels for thyroid hormones (our own or replacement ones) to work in our cells
Also do you know if you have had thyroid antibodies checked? There are two sorts TPO Ab and TG Ab. (Thyroid peroxidase and thyroglobulin) Both need checking, if either, or both antibodies are high this means autoimmune thyroid - called Hashimoto's the most common cause in UK of being hypo.
TPO is rarely checked and TG almost never checked. More common to have high TPO or high TPO AND high TG, but negative TPO and raised TG is possible, though rarer.
ALWAYS Make sure you get the actual figures from tests (including ranges - figures in brackets). You are entitled to copies of your own results.
When you get further results suggest you make a new post on here and members can offer advice on results
If you can not get GP to do these tests, then like many of us, you can get them done privately
Special offer at moment
Usual advice on ALL thyroid tests, is to do early in morning, ideally before 9am. No food or drink beforehand (other than water) If you are taking Levo, then don't take it in 24 hours before (take straight after). This way your tests are always consistent, and it will show highest TSH, and as this is mainly all the medics decide dose on, best idea is to keep result as high as possible
Are you aware that thyroxine must be taken on an empty stomach and then nothing apart from water for at least an hour after. (No coffee or tea) Many take on waking, but can be more convenient and recent research, suggests perhaps is more effective taken at bedtime. (Must be at least two hours after eating)
