Objective To establish an algorithm for first-trimester combined screening for trisomy 21 with biochemical testing from 7 to 14 weeks ’ gestation and ultrasound testing at 11–13 weeks. Methods This was a multicenter study of 886 pregnancies with trisomy 21 and 222 475 unaffected pregnancies with measurements of free β-human chorionic gonadotropin (β-hCG) and pregnancy-associated plasma protein-A (PAPP-A) at 7–14 weeks ’ gestation. Multiple regression modeling of log-transformed marker values was used to produce log multiples of the median (MoM) values for PAPP-A and free β-hCG. The models included terms for the center attended and the machine use
