Hi
Just had my bloods done and my tsh is 0.16 with normal t4 and t3 what does this mean?
Back in December my tsh was 0.28 why has it dropped more? I had my gallbladder removed in December could it be related? I have anxiety, and just really don't feel like me. Any advice??
Thanks
What is your T4 and T3 with ranges?
You have to put the ranges after the results of your test. The reason is that labs differ and so do the ranges so it is necessary for them to be stated.
Get a print-out from the surgery after each thyroid blood test for your own records and to post if you have a query.
The word 'normal' is meaningless with regard to thyroid hormones particularly if patient doesn't feel normal.
Your TSH is low but that is from the pituitary gland and doesn't give much information about how your T4 or T3 which is the important ones but the most important is your Free T4 and Free T3 and I doubt GP has tested these.
If you've not had B12, Vit D, iron, ferritin and folate tested recently, ask for these to be done as well.
Blood tests should be the very earliest, fasting (you can drink water) and allow 24 hours approx between your last dose of levo and the test and take afterwards.
If you take it before your blood test it skews the results, so ask GP to do another test as you want to feel much better and have joined the NHS Choices for info on dysfunctions of the thyroid gland. If doctor will do another blood test ask for a Full Thyroid Function Test which is, TSH, T4, T3, Free T4, Free T3 and thyroid antibodies (if you've not had antibodies done previously).
Always get a print-out of your results for your own records.
As you had gallbladder op recently, your B12 may have really lowered
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.
If you have Hashimoto's then you may find adopting 100% gluten free diet can really help reduce symptoms, and may lower antibodies slowly over time too.
Hi I have my results and doctor has referred me urgently to an endocrine specialist.I'm am not on any medication my results are
Tsh 0.16
Free t3 5.1 (within normal range)
