This application allows estimation of risks for fetal macrosomia (birth weight >90th percentile for gestational age) from a combination of maternal characteristics, previous obstetric history and findings at 11-13 weeks .

MoM values for PAPP-A and free ß-hCG depend on maternal characteristics but also on the equipment and reagents used at a specific laboratory; you will therefore need to obtain the MoM values from your laboratory.
