What do your SHBG levels mean?
The short answer
Nobody we follow has said what your SHBG should be. It comes up on the shows, but never with a number.
Your lab prints 18–144 nmol/L. That range exists to catch disease, not to describe your best.
Labs print different ranges by sex: about 18–144 nmol/L for women and 10–57 for men.
What SHBG measures
A protein that binds sex hormones and holds them inactive.
It decides how much of your testosterone and oestrogen your body can reach. So it changes what a total hormone value means.
