Calculate free estradiol?

[krm]

Hi guys

it seems to be common to calculate free T from total T, Albumin, SHBG.
Is there a similar formula for free E?

Couldn't find much about that on google...

I'm not aware of anything out there for Free E2 for calculation purposes. There have been no real studies as of yet but it is a topic getting more and more attention.

Discounted Labs just recently added a Free Estradiol lab test.

Maybe someone has more info on this than I am aware of.

@MarkM Not in the US unforutnately (I'm in Switzerland), so can't go to DiscountedLabs...
@madman Thanks a ton! Interesting read!

TLDR; => "Technically you can, assays of influencing factors vary so much though that it's impractical and results woulnd't be comparable."

Not a calculation that I know of.
