Cell-Free Fetal DNA for Genetic Evaluation in Copenhagen Pregnancy Loss Study (COPL): A Prospective Cohort Study

Abstract

(Abstracted from Lancet 2023;401:762–771Spontaneous pregnancy loss occurs in approximately 1 in 4 pregnancies; however, diagnostic workup is mostly restricted to women with recurrent pregnancy loss. The lack of workup on first pregnancy loss is likely a result of the high de novo fetal aneuploidy rate; however, this ignores the association of euploid pregnancy loss with an increased risk of future losses.
