Importance of Bio T and E2 Sensitive Assay?

[JustOne]

How important is it to have Bioavailable T instead of Free T done, and Ultra sensitive assay for E2.

I just called up the 2 biggest Labs in australia and asked them if they did those tests, neither of them have ever heard of Bioavailable T. and The 1st one said there E2 goes as sensitive as 18 pmol/L wich doesnt make sense to me.
And I wasnt talking to reception, I think I was actually speaking to the poeple who look at the blood cause I got switched through from the reception and I could hear them reading out results in the background.

It's better but if you can't get them it's not the end of the world Total T is the next best and if your below 18 your going to low.
