In brief: Screening vs confirm

Blood screening is a relatively non invasive way to get information on significant problems but by definition it is screening.
Screening is an effort to narrow down the list of people that need a specific confirmatory test.By example, for every 1000 screened, 10 may be positive, and offered the amnio to find 1 true positive. An amnio is more invasive & risky but gives more definitive results.
