I am very new to this, so any help is welcomed. I have now been referred to an Endocrinologist but have been borderline overactive for a while (GP wouldn't treat or refer until now.) My ESR and Immunoglobin are also heightened. I have always had blood tests late afternoon, can this affect things?
TSH: 0.63
T4: 24.8
ESR: 38 (up to 20 is normal)
Immunoglobin: 4.55 (0.8 - 2.8 is normal)
I have all the normal overactive symptoms - exhausted, weight loss, increased frequency for the toilet, anxiety, palpitations, brain fog etc. Most recently a throbbing to my throat - what's all that about?

Please could you add ranges. Ranges vary between labs.
How long is a while? Over what precious of time? Do you have previous results to compare?
Your results show low TSH & high FT4 by most ranges, but this shows an elevation not dangerously high levels.
With Graves the most common cause of continuous hyper you would expect to see suppressed / undetectable TSH (<0.01) and FT4 is the 40s.
Although any continuous elevation will need to be addressed. So it’s good you are being referred to endocrinologist.
Your FT3 also needs to be tested, this is the active thyroid hormone, it can be out of balance.
ESR is non specific, you have inflammation occurring, but test cant pinpoint why or where, autoimmune is often a strong possibility.
Was it TSI thyroid stimulating immunoglobulin? The range doesn’t look right for that test.
As usually immunoglobulin is categorised to A, D, E, G, M. but these are less useful in terms of thyroid.
Your doctors should be establishing why your levels are showing hyper. Usually testing thyroid antibodies is first step.
TPO & TG antibodies are high with Hashimoto’s \ autoimmune thyroiditis. This can cause fluctuations in levels early on. Can also be positive with Graves.
If hyper Graves is suspected this must be confirmed by positive TSI or TRAb.
Treating low TSH / High FT4 as assumed hyper, without investigating why levels are high is not good approach. If rise is transient & will naturally drop anti thyroid medication will hasten the decline.
I haven't had any further specific tests. My T4 has been creeping up and TSH going down over the last few years, however even though i have had symptoms and my Dad had Graves, my GP refused to refer me, they're only now referring me as i am now deemed to be out of their normal range, however they haven't told me the ranges.
A gradual increase such as this is what happened to me.
Over at least 4 years my frees were climbing, although my TSH became suppressed early on. My FT3 was similar to you level which just above range but FT4 was nearly double.
Is wasn’t closely monitored - I found all this out later when searching records.
I had ultrasound & had uptake scan to confirm a hyper functioning nodule, as antibodies were negative.
My father has thyroidectomy for hyper but wasn’t ever told the cause.
You can request a print outs of results via reception, most useful is to set up online access to GP records. See what’s access is available at your practice.
Hope your upcoming appointment goes well, & you get some answers.
