Fluctuating test results

[Cronx]

Hi all,

I'm currently undiagnosed, but have a very strong family history so it's always been on my mind. I've also got all the symptoms and am so sick of sleeping all the time!

My first blood test was 6 months ago and my TSH was 4.6 (range 0.27 - 4.2)

The GP said all was fine and sent me away. I pushed back and he decided to do another test 'to check it's not a fluke' and test came back 4.8 (0.27-4.2). This time also t4 which was 14 (12.0 - 22). Because t4 was in range he send me away.

I then changed GPs 3 months ago and got tested again. This time it was 3.7 (0.27-4.2). My GP talked me through everything and said she would test again in 2 months and if it was over 4.2 she would prescribe medication. We're now at the 2 month point and I was short on time so I bought a medichecks kit 2 weeks ago and my results came back as 5.2 (0.27-4.2). Managed to get an appointment with my GP who sent me for NHS blood tests and I've just got a text to say 'all normal, no action required'. so annoying!

They haven't told me the number as apparently it was too early to be on the system but my GP wasn't in work today so I wouldn't be surprised if it was slightly high and a different GP just marked it as fine.

Regardless, is it normal for TSH to fluctuate like this? Am I wrong for pushing this when my last NHS test came back 3.7 or is the medichecks one accurate enough to keep trying?

I feel like I've been told for so long that I need antidepressants that I'm not sure whether to start believing the symptoms are psychological, not physical.

Cronx You need thyroid antibodies checking. Did you not do a Medichecks test that includes Antibodies? Antibodies will cause fluctuations in results.

Ah no I haven't. I'll definitely look into that. Thank you

NHS only seem to do TPO, Medichecks test both TPO and TG antibodies.

You are hypo when your TSH is consistantly over 3.

Were all your blood tests done at the same time of day? TSH is highest early in the morning, and decreases throughout the day. It also decreases after eating. So, early-morning, fasting blood draws are best.

I doubt you need antidepressants, keep pushing for thyroid!

What are your other MediCheck results as that could be very telling.

I only did the cheapest test through medichecks (so TSH and T4) but I'm going to order the full one now I have more of an understanding of what the results will tell me!
