“…All sonographers ( n = 39) at the eight study sites underwent rigorous training and standardization. In accordance with the protocol, CRL and other fetal biometry measures were assessed for quality; the former were also reviewed blindly by our collaborators at the Société Française pour l'Amélioration des Pratiques Echographiques.…”

“…and thus reinforces the utility of this marker. However, measurement of CRL is sometimes tricky, and if it is underestimated the BPD percentile may be overestimated and would therefore engender false‐negative results. We believe that a direct comparison of BPD and TAD measurements is a simple and rapid method for all operators, regardless of their level of expertise.…”

Objective To create international symphysis-fundal height standards derived from pregnancies of healthy women with good maternal and perinatal outcomes.Design Prospective longitudinal observational study.Setting Eight geographically diverse urban regions in Brazil, China, India, Italy, Kenya, Oman, United Kingdom, and United States.Participants Healthy, well nourished pregnant women enrolled into the Fetal Growth Longitudinal Study component of the INTERGROWTH-21st Project at 9-14 weeks’ gestation, and followed up until birth.Main outcome measures Symphysis-fundal height was measured every five weeks from 14 weeks’ gestation until birth using standardised methods and dedicated research staff who were blinded to the symphysis-fundal height measurements by turning the tape measure so that numbers were not visible during examination. The best fitting curve was selected using second degree fractional polynomials and further modelled in a multilevel framework to account for the longitudinal design of the study.Results Of 13 108 women screened in the first trimester, 4607 (35.1%) met the study entry criteria. Of the eligible women, 4321 (93.8%) had pregnancies without major complications and delivered live singletons without congenital malformations. The median number of symphysis-fundal height measurements was 5.0 (range 1-7); 3976 (92.0%) women had four or more measurements. Symphysis-fundal height measurements increased almost linearly with gestational age; data were used to determine fitted 3rd, 50th, and 97th centile curves, which showed excellent agreement with observed values.Conclusions This study presents international standards to measure symphysis-fundal height as a first level screening tool for fetal growth disturbances.
