Contingent screening for Down syndrome is an efficient alternative to non‐disclosure sequential screening

1 Oct 2004

Abstract excerpt

OBJECTIVE: To present a first and second trimester Down syndrome screening strategy, whereby second-trimester marker determination is contingent on the first-trimester results. Unlike non-disclosure sequential screening ('the Integrated test'), which requires all women to have markers in both trimesters, this allows a large proportion of the women to complete screening in the first trimester. METHODS: Two...
