Predicting complications of pregnancy with first‐trimester maternal serum free‐βhCG, PAPP‐A and inhibin‐A

Low PAPP-A level is associated with the delivery of an SGA baby and high PAPP-A with the delivery of an LGA baby. High inhibin-A is associated with preterm delivery before 34 weeks. Feto-placental products in the first trimester do not prove to be useful as a screening tool for predicting pregnancy complications.
