Almost certainly not, as stopping T3 would cause spike in cortisol to try to compensate for lack of T3

If taking vitamin B complex, or biotin you probably need to stop this a week before test

Thanks slowdragon ❤️Can I continue with my vitamin D sorry should have mentioned that to.. 😕 ❤️❤️❤️

The ACTH blood test needs to go on ice straightaway so make sure they do that.

Hi paulineS❤️Thanks for that info, I'm not bothered about the test just all the hurdles I will have to jump to get their, taxi to train station, train to city, taxi to hospital then covid rules whilst in hospital 😷 then all that again to come home, and I can see my local hospital from where I live,, 🙄🙄 makes no sense 🤔

It's probably because it's a specialist test that your local hospital can't do :(

Stress of journey will almost certainly raise your cortisol levels then

Presumably appointment is 9am or earlier?

Hi slowdragon ❤️Appointment is 8.20AM....👍

Please make sure that you have not taken any Biotion either on it's own or part of a multi vitamin. You must stop any HRT or Biotin at least 6 weeks before this test.

Hi thanks heathermr❤️

I can't take HRT... And only vitamin I take is vitamin D do u think I should stop this also I'm worried about my T3 10 mg.. Split????

Vitamin D is fine so continue as normal. Your last dose of T3 should be at least 12 hours before the test. Personally I would make sure my last dose of T3 would be 24 hours before the test even if I had to crawl to the test! These Endos dont need any excuses to convince you to stop T3.
