Answer 12

A protein produced by the fetus and placenta

Question 13

Inhibin A (part of Quad Marker Screening)

Answer 13

A protein produced by the ovaries and placenta

Question 14

Human chorionic gonadotropin (hCG) (part of Quad Marker Screening)

Answer 14

A hormone produced by the placenta

Question 15

Quad Marker and Alpha-Fetoprotein (AFP) ScreeningWhat is the purpose?..to determine?

Answer 15

Ascertains info about the likelihood of the defects. It does not diagnose the actual defect. It may be performed instead of AFP.
