This test was actually never intended as a screening test for all pregnant women (just for high risk women), but doctors pushed for it to avoid lawsuits from women who did end up having babies with problems.

So they specifically worked on a screening test to be administered to those under 35, to catch more cases.
|When the AFP-screening test kit was first introduced, the FDA regulated and allowed its use only in research settings. However, pressure from physicians and laboratories prompted the FDA to withdraw regulating screening. The American College of Obstetricians and Gynecologists (ACOG) advised its members to offer the test to all pregnany women as part of a liability alert. This alert was for the benefit of doctors, not women. It was mean to prevent lawsuit.|
