A screen negative result means that your likelihood of having a child with a neural tube defect is one in 1,000 or less. It also means that your likelihood of having a child with Down syndrome is less than that of a 35-year-old woman. It is never possible to be sure that your baby is going to be normal.

What is screen positive for open NTD?

A screen positive result means that you are in a group with an increased likelihood of having a baby with an open neural tube defect. If the result is screen positive, you will be offered an ultrasound examination after 16 weeks of pregnancy, and possibly an amniocentesis.

When can you tell if your baby has neural tube defects?

Neural tube defects may be diagnosed during the ultrasound scan that is carried out around week 12 of the pregnancy or, more likely, during the anomaly scan that is carried out at around weeks 18 to 20.
