Prenatal Diagnostics
Guidance during your pregnancy
NIPT is a DNA-based blood screening test that assesses the probability of chromosomal conditions as early as 10 weeks in pregnancy.
A DNA-based technology
When you are pregnant, your blood contains fragments of your baby’s DNA. NIPT analyzes DNA in a sample of your blood to evaluate the probability of trisomy, sex chromosome aneuploidies, microdeletions and gender.
As early as 10 weeks
NIPT requires a single blood draw. It can be done as early as 10 weeks in pregnancy.
Ultrasound should be performed before drawing the blood sample. In part to determine the pregnancy duration and in part to see the number of fetuses. There are some advantages to doing the ultrasound in week 12 when the baby’s development and organs are more easily evaluated.
