What to Expect

Overview

Although each patient receives specific instructions on how to prepare for various screenings, Holy Name's team of maternal-fetal experts has compiled common pre-test instructions to ensure each screening produces correct results.

• Amniocentesis: Drink 3 (8oz.) glasses of non-carbonated fluid. Finish drinking one hour prior to the ultrasound test. Do not urinate - a full bladder is required. A light breakfast is recommended.
• Chorionic villus sampling (CVS): Follow the directions for amniocentesis.
• First trimester ultrasound: Follow the directions for amniocentesis.
• First trimester transvaginal ultrasound (up to 12 weeks pregnant): No preparation required
• Non-stress or biophysical profile: No preparation required
• Second trimester ultrasound: Follow the directions for amniocentesis
