How is triple screening in a twin pregnancy?

By Zaira Salvador B.Sc., M.Sc. (embryologist).
Last Update: 02/08/2022

Combined first trimester screening in multiple pregnancies depends on the type of gestation. In the case of a two-chorionic gestation, the nuchal translucency will be assessed for each of the fetuses and two different risk indexes will be calculated. In contrast, in a singleton gestation, only one risk index is calculated taking into account the upper nuchal translucency.
