"It is encouraging to have a prenatal biologic measure that predicts postpartum depression," Sheeder said. "However, I am not sure about the practicality of using pCRH as a screening tool. It has been shown that prenatal depression is predictive of postpartum depression, and it is easier and cheaper to do that type of screening than pCRH in most clinical settings."
The National Women's Health Information Center has more on depression and pregnancy.
