Nuchal Translucency

GVG Imaging is a certified practice for First Trimester Prenatal Screening. "Early Screen" is the most accurate, earliest, and safest prenatal screening available with the fewest false positive results. It is approved by the American College of Obstetricians and Gynecologist.

"Early Screen" uses a maternal blood test combined with an ultrasound measurement. The ultrasound is performed between 11 and 13.6 weeks to measure fluid on the babys neck, called the nuchal translucency. A finger-prick blood test measures two pregnancy proteins in the mother's blood, freeBeta-hCG and PAPP-A.

The blood test with the nuchal translucency identifies 91% of Down syndrome, 97% of trisomy 18, 40% of heart defects, and some other birth defects. "Early Screen" may be offered to all pregnant women.

Each patient's specific results is affected by:

• Exactly how far along in your pregnancy you are on the day the blood sample is taken and the ultrasound is performed
• Your weight, ethnic background, and age
• Whether you are insulin-dependent diabetic or take certain types of medications
• Whether a close relative has Down Syndrome
• This screening test can not diagnose or rule out any specific condition. It is only used to evaluate your risk for this particular pregnancy.
• Results are typically available within a week. Your care giver will contact you with results.

Preparations for Nuchal Translucency Ultrasound

• Please drink 24 ounces of clear fluid one(1) hour before your appointment.
• Please DO NOT empty your bladder before the ultrasound.
• A full bladder is necessary to better visualize the baby if it is positioned low within your pelvis.
• Plan on 45 minutes to 1 hour to complete this exam.
