AIM: To examine the performance of the combined First Trimester Screening (cFTS) algorithm when outliers of 4 risk parameters (maternal age, nuchal translucency (NT) thickness, PAPP-A and ß-hCG) were included in the classification of "high-risk". METHODS: A retrospective analysis of singleton pregnancies undergoing cFTS between 2008 and 2011 in Denmark. Abnormal karyotypes were classified as trisomy 21 (T21), trisomy 13 (T13) and trisomy 18 (T18), sex chromosome aberrations and atypical abnormal karyotypes.
