  • The quad screen test is a maternal blood screening test that looks for four specific substances: AFP, hCG, Estriol, and Inhibin-A. AFP: alpha-fetoprotein is a protein that is produced by the fetus
    hCG: human chorionic gonadotropin is a hormone produced within the placenta
    Estriol: estriol is an estrogen produced by both the fetus and the placenta
    Inhibin-A: inhibin-A is a protein produced by the placenta and ovaries
    The screen is essentially the same as the screening tests that look for only three substances, except the likelihood of identifying pregnancies at risk for Down Syndrome.

  • I had that blood test done to detect Down Syndrome and had the ultrasound done for my first trimester screening. The results were NEG for Down Syndrome, but my baby was born with Down Syndrome anyway. I have not and will not EVER get that test done again because it won't matter anyway.
