Hello all,
I'm not sure where I could find this out but I had a blood test done on 4th Jun with Thriva which came back as borderline hypothyroidism.
Blood test done on 27th August at the drs and it's borderline hyperthyroidism.
Is this common? Does a thyroid result usually fluctuate like this? I'm back in Dec for another blood test.
Thank you!

here are more knowledgeable people than myself on here but They'll need you to post all your test results to get the best advice 
And what thyroid meds you are taking.

Have you had thyroid antibodies tested? If not ask for Thyroid Peroxidase and Thyroglobulin. Thriva probably do these in a thyroid test bundle, Medichecks and Blue Horizon do.
Hi geworgie3008. Can you post more details, like both blood results?
What the Dr’s consider Hypo or hyper can vary greatly. Only numbers tell the story.
Thanks everyone.
Thriva: TSH 6.03 FT4: 16
Drs: literally all the receptionist could tell me was my result was 5.1 and 'my range is 3-5'. So I don't know what that result refers to. Perhaps TSH?
Meaninglesss without ranges, but that looks hypo - free t3 is probably low causing TSH to rise (as free T4 might be OK, but impossible to tell without ranges). If you are in the UK you are legally entitled to a printout of your results - don't take no for an answer.
That's so annoying re the doctors. You can ask for a print-out which will give more detail. That's not a hyper reading though. Both of those are potentially hypo but did you not get more details from Thriva - the details are important to get the best advice on here I saw an endo when my TSH was only 4.1 because I felt to ill - but I also had high anti-bodies suggesting Hashimotos disease. In other countries they would treat this level of TSH if you had symptoms. You should get some really good advice on here soon though.
It sounds like they were both TSH readings (with the range for the one done via the doctor more likely to be 0.3 to 5). In which case, definitely not hyperthyroidism. They’re both hypothyroid results.
I wouldn't say that a TSH of 6.01 and another of 5.3 some 12 weeks later is necessarily fluctuating, especially if you had the bloods drawn at different times of the day -TSH levels rise and fall throughout each diurnal cycle. But neither are indicative of hyperthyroidism, whether borderline or overt. Put simplistically, with primary thyroid disorders, hypothyroidism will generally be accompanied by high in, or above, reference range TSH and low in range/below range FT4; whilst hyperthyroidism will have below range TSH and above range FT4. Without knowing the reference range for your FT4 result of 16, it's not possible to guess at where it sits within the reference interval, as labs vary in terms of what reference intervals are applied, especially for FT4. Thriva will have provided you with both the actual reference intervals for each test carried out, and the 'optimal' parameters within the intervals, whilst the NHS tests will simply have the reference intervals, and it's important to always quote both result and reference interval when asking for members to comment. You are legally entitled to a free printout from your surgery, of any test carried out; just ask at reception for a copy to be printed out for you.
If you have autoimmune thyroid disease (hashimotos) it is quite usual to have this type of blood result. If you post your actual results with ranges, people can advise. The so-called subclinical results usually just mean that TSH has changed, which can happen because of interference with the tests (for example, taking a biotin supplement or having certain antibodies or dven just having a test at a different time of day), so really need to see the actual results.
Hello all! Thank you for all your answers. I intended to come back and reply but life happened and then before I knew it it was time for the repeat test to be done so thought I should wait for that to be done first!
So! I asked for a print out this time.
In Nov: TSH level was 7.54 (range 0.3-5.0)
T4 level was 14.7 (range 12.0-22.0)
In Oct: THRIVA- TSH level was 7.73 (range 0.3-9.9)
T4 level was 15.7 (range 12-17)
In Aug: TSH level was 5.1 not sure on the T4 though.
This seems like a big increase in 12 weeks.
Is that usual?
