PreNatal Screening is the process in which many genetic abnormalities and birth defects can be detected before birth. But when someone screens a fetus, who are they doing it for?
It seems like there are two obvious possible answers. The first one is the baby, the other is for the mother or parents. But neither are terribly satisfying answers.
Lets say for the sake of argument that Milly gets a prenatal screening on her fetus. The test returns a positive hit for Down's syndrome, and for the sake of argument, its not a false positive. If this is for the sake of the fetus, then the parents should now be either marshalling resources to take the best care they can for their baby, or terminate the preganacy to spare it suffering.
But how can an abortion be in the interest of the baby? Its not like Down's syndrome is so debilitating that the baby cannot have a happy life.
If the screening is for the parent's interest, then the preganacy should be terminated, and the parents can try again, which would save them a huge amount of money and medical resources that could be spent on other people.
If its for the interest of the baby, then shouldn't we mandate that all women have prenatal screenings, to ensure that the parents can marshal the resources needed for the disabled baby if it is disabled?
If its in the interest of the parents, then how could we possibly mandate such an invasive test?
