How you prepare

By Mayo Clinic Staff

If you are about 24 weeks pregnant, you will be asked to avoid eating or drinking after midnight the night before cordocentesis. This is because certain complications caused by the procedure might require an emergency C-section. Ask your health care provider for guidance.

You might want to ask your partner or another close contact to accompany you to the appointment for emotional support or to drive you home afterward.
