Hello List members
I have recently performed a combined testosterone / SHBG
exercise in the UK NEQAS for steroid hormones. This included
requests for information on derived (free) androgen/testosterone
indices. The replies are currently being analysed. I will be
publishing a detailed report to participants and will post a brief
summary on the list in due course. Of course, I will not be able to
identify any individual user of any particular method, but can put
people in touch.
