The baby can be measured as early as 5 or 6 weeks after the motherâs last menstrual period. Measuring the baby using ultrasound is most accurate in early pregnancy. It becomes less accurate later in pregnancy. The best time to estimate gestational age using ultrasound is between the 8th and 18th weeks of pregnancy. The most accurate way to determine gestational age is using the first day of the womanâs last menstrual period and confirming this gestational age with the measurement from an ultrasound exam.
To determine the approximate gestational age of a newborn, youâll assess six neuromuscular and six physical characteristics. This assessment, the New Ballard Score, is appropriate for newborns from 20 to 44 weeks of gestation, with the characteristics to assess varying with the stage of maturity.Each parameter scores from minus 2 to 5, with the cumulative score correlating with a gestational age between 26 and 44 weeks.Timing of the gestational assessment influences the accuracy of its results. For newborns younger than 26 gestational weeks, perform the assessment sooner than 12 hours after birth.ach parameter scores from minus 2 to 5, with the cumulative score correlating with a gestational age between 26 and 44 weeks.
