I had thyroid testing in Surrey (not for infertility) and it cost me over £200. Thyroid tests are more expensive than other routine blood tests. However if it puts your mind at rest or uncovers something it is probably worth doing.
Do you have any other symptoms?
Good luck.

Your GP might help. One thing worth noting is that general normal levels of tsh(?) are good between 0.3 and over 4. Mine was supposedly normal but now that I'm about to have IVF, I've been put on levothyroxine - apparently for conception and pregnancy, you want it under 2.5. I also know someone whose thyroid was supposedly ok but she struggled to conceive for a long time. Once she was put on Levothyroxine, she conceived straight away. And had another baby shortly after... So it's worth checking. You could also check vit D levels- they are meant to be pretty crucial to conception too.

I just had some thyroid tests done by thriva, they send you a pack out and you do a fingerprick sample and send it back. It was £70ish. I then took the results to my GP who has referred me to an endocrinologist (GP has previously only done a simple tsh test, the private test was much more extensive and showed an issue with antibodies which doesn't always raise tsh levels). Well worth the money for me!

Hi, sorry to jump in here but was just about to post a thread about thyroid issues and saw yours...
Basically we are unexplained secondary infertility and have 2 failed ivf cycles behind us now. My DS was naturally conceived (he will be 4 in August) but no luck since then... I have a list of symptoms which are relatively mild, but made me suspect that thyroid could be a problem, so I got it tested using 'blue horizons' test (online). They send you a test tube to collect a pin prick sample in. I found doing the sample quite tricky as you need to get quite a bit of blood and mine took ages, but I got there in the end.
Anyway, my test came back 'normal' however when I look into it more I don't think they are 'optimal'. Is there anyone on here who has had normal but not optimal levels and has gone to their gp about it and been taken seriously? Thanks!

I should add I tested for TSH, free t3 & free T4.

You could also test for thyroid antibodies (Hashimoto's) - that can be a fertility problem but I don't think it makes a difference to the other levels.

I managed to get my thyroid tests done with a GP referral. He suggested getting those done even though otherwise he's infuriatingly obstructive (told me after ttc for 2 years that I was young at 36 and should carry on trying and refused to refer further...). So who knows, your GP might just be willing to help...

I think I've had all the tests that are listed as finger prick ones done.

When you had your tests done last time round, how thorough were they? Have you considered going to a different clinic so that a new doctor can decide which tests are worth pursuing? Trying to DIY your diagnosis might be a bit tricky if you aren't an expert.

Have you asked your GP to test your thyroid?

Your TSH should be under 2.5 for TTC, although the range for normal life is 0.3-5, and it isn't always easy to get a GP to put you on meds if you are between 2.5-5

If you want to go privately, find the nearest private GP to you and book an appointment with them and ask for a thyroid function test to cover TSH, T3, free T4 and thyroid antibodies
Appointment, tests and follow up appointment will be around £150-200 depending on where you go
This would be better than a prick test because a private GP will be able to prescribe you the medication, where as the prick test company won't, and if you're in the 2.5-5 range, a GP might not either

Depending on the results, you might want to go back to your GP and ask for a referral to an endocrinologist

I think its worth asking your own gp.
As your sister had a problem and you have ttc for a year with miscarriages.
Im surprised thyroid wasnt tested for you when ttc #1.
