Can a Psychologist PhD write a referral to an endocrinologist?
If a therapist can a Phd should be able too :)
You might ask them :)
hugs
Most likely - might ultimately depend on the endo and any local laws and statutes. In Australia for example if you want to be part of the public health system benefits it has to be written by a psych (a therapist won't cut it). You should ask them.
