I.G.
Mine did. I had the whole blood panel done and an ultrasound (this was elective from my side, and done by a U/S tech at the MW office and evaluated by a perinatologist who just sent the results to my MW).
The only thing she would have had to refer me for was an amnio (which I didn't have) and I did see an OB for a version, since my baby was breech.
I still see my midwife for my annual exams and have no intentions of EVER seeing an OB/GYN again, unless I have an illness that requires it.
I feel she truly provides "well woman care".
Good luck!
