How Do I Prepare for an Amniocentesis?
You should drink two to three 8 oz. glasses of water one hour prior to your ultrasound test. A full bladder is necessary for the ultrasound procedure.
Do not take any aspirin or aspirin-containing products five (5) days prior to the amniocentesis procedure, do not take Lovenox 48 hours prior to the procedure, and do not take heparin 24 hours prior to the procedure
