We correlate serum AAT levels to the essential feto\u2010maternal parameters for an earlier and cost\u2013benefit diagnostic method, thus distinguishing between FGR and normal birth weight in pre\u2010eclamptic women.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>An observational study conducted at the University hospital recruited 100 pregnant women in 32\/34\u2009weeks of a singleton single tone pregnancy; all were pre\u2010eclampsia cases. All were tested by laboratory and ultrasound examination. Two sets of data were collected; one is maternal parameters such as blood pressure (BP), maternal serum AAT mean platelet volume (MPV), platelet distribution width (PDW), and serum uric acid levels, and the other is fetal parameters such as amniotic fluid index (AFI), fetal weight centile and estimated fetal weight.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A strong negative correlation proved between serum levels of AAT and all study variables except fetal weight (systolic BP, diastolic BP, MPV, PDW, serum uric acid, fetal weight percentile, and AFI) with a correlation coefficient of; \u22120.95, \u22120.95, \u22120.85, \u22120.93, \u22120.91, \u22120.94, and \u22120.93 respectively. The cut\u2010off value for AAT 0.013 mg\/ml showed the highest sensitivity and specificity as a diagnostic marker for FGR. Area under the curve was 0.99.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>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\u2010eclamptic patients and may serve as a helpful tool in distinguishing between FGR and normal birth weight babies, pending further validation in feto\u2010maternal
