Monochorionic twin pregnancies mimicking MA gestations, such as twin\u2010twin transfusion syndrome, were excluded. Complicated MA gestations and higher\u2010order multifetal gestations involving an MA pair were excluded. Thirty subjects were followed with serial amniotic fluid index (AFI) measurements from 15 to 32\u2009weeks gestation. Using each AFI measurement as a unique data point, a quadratic regression model and a multi\u2010level growth model were developed against gestational age (GA), providing a predicted AFI at each completed week, with a 95% confidence interval.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The quadratic regression least squares and multi\u2010level growth models yielded the same curve comparing the AFI to the GA. Figure\u20091 depicts the model with the 95% confidence interval for normal amniotic fluid volume by GA for normal MA twins. Table\u20092 shows the 5th, 50th, and 95th percentiles for AFI by week from 15 to 32\u2009weeks.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We have generated normative data for amniotic fluid volume across gestation in uncomplicated MA twins.
