Dear Kathleen, There are a few blood tests that can be run to evaluate for the etiology of failed lactogenesis. They are: TSH, prolactin, HcG and testosterone. I am not aware of wellbutrin affecting prolactin levels but doesn't mean we can't document a first. IN light of the recent lactnet discussions, you may also consider obtaining a B12 level.
