This is a 27 yr old G2P1 at 20 5/7 weeks. She was referred for evaluation because of a second trimester ‘quad’ screen which identified an increased risk for open neural tube defects. The results of the ‘quad’ screen are as follows:

Trisomy 1:3473
ONTD 1:10

The individual analyte levels are:

AFP8 8.73 MOM
Hcg 4.26 MOM
DIA 2.95 MOM
uE3  0.58 MOM

Selected images from the 20 week ultrasound are given below. Overall fetal biometry was appropriate for gestational age with an AUA of 20 wks 1 day.

In addition to ultrasound, amniocentesis was performed. Fluid results include:

AChE negative
Fetal karyotype 46 XX

Further testing performed on the fluid will be discussed when the answer is revealed next week. Good luck
