Take T3 on day of FT3 test

[Guest guest]

Hi,

My GP's lab refuses to do a Free T3 blood test for me and so I'm sending a blood

sample to a private lab instead.

I'm doing the test because I take T3 and I wish to know whether I'm taking too

much or too little.

In view of why I'm doing the test would it be better for me to take it on the

morning of the test, or not take it for 24 hours? I'm not bothered about my GP

thinking I'm taking too much ~ only to know where I am with it.

It would be really helpful to have some views on this please.

Thanks!
