Test Usage
Measurement of SHBG can be an
important indicator of an
excessive/chronic androgenic action where androgen elvels are
normal, but where clinical symptoms would seem to indicate
androgen
in excess. SHBG is a useful supplementary
parameter in the
determination of androgen where a relatively high concentration
of
free androgen (e.g. testosterone) is suspected.
