Remember that "free test" might not be as significant as we once thought. Sure test that isn't esterified is significant, but test bound to SHBG isn't really "deactivated" like once thought, there is a receptor on the outside of cells that SHBG with hormone bound to it fits into, this receptor then actively transports the SHBG+hormone to the appropriate receptor inside the cell and starts transcription. SHBG is much more complex than once thought. You can google SHBG membrane receptor if you want to verify this information. There is a really good write up on it somewhere as well, maybe someone has a link, it used to be on Dat's forum.
