A highly specialized screening test to help evaluate the health of your unborn baby
One important screening test available to our pregnant patients is quad screening, a type of diagnostic screening tool that is performed on a blood sample obtained during the 15th and 20th week of pregnancy. A quad screening looks for four specific substances:
- AFP (alpha-fetoprotein): a protein produced by the fetus
- hCG (human chorionic gonadotropin): a hormone produced within the placenta
- Estriol: an estrogen produced by both the fetus and the placenta
- Inhibin-A: a protein produced by the placenta and ovaries
The quad screen detects about 90% of fetuses with open structural defects such as neural tube defects or abdominal wall defects, as well as approximately 60% of babies with Down syndrome and Trisomy18.
