Background There is a need to standardize monitoring in obstetric research of twin
pregnancies. Identification of birth weight discordance (BWD), defined as a difference in the
birth weights of twins, is a well‐documented phenomenon in twin pregnancies. Ultrasound
for the diagnosis of BWD informs complex decision making including whether to intervene
medically (via laser photo coagulation) or deliver the twins to avoid fetal morbidities or even
death. The question is, how accurate is this measurement? Objectives To determine the …

Background
There is a need to standardize monitoring in obstetric research of twin pregnancies. Identification of birth weight discordance (BWD), defined as a difference in the birth weights of twins, is a well‐documented phenomenon in twin pregnancies. Ultrasound for the diagnosis of BWD informs complex decision making including whether to intervene medically (via laser photo coagulation) or deliver the twins to avoid fetal morbidities or even death. The question is, how accurate is this measurement?
Objectives
To determine the diagnostic accuracy (sensitivity and specificity) of ultrasound estimated fetal weight discordance (EFWD) of 20% and 25% using different estimated biometric ultrasound measurements compared with the actual BWD as the reference standard in twin pregnancies.
