Maternal alpha-1-antitrypsin as a noval marker for growth restriction in pre-eclampsia.

Negative correlations between maternal serum AAT and fetal parameters used to assess FGR were confirmed, suggesting that AAT is closely related to the pathophysiology of FGR among pre-eclamptic patients and may serve as a helpful tool in distinguishing between FGR and normal birth weight babies, pending further validation in feto-maternal outcomes.
