I unearthed that the fresh new devices used various a way to manage discrepancies anywhere between last-menstrual-period-created and you can ultrasound-centered gestational ages; this may also take place in most other equivalent setup. Interestingly, none federal neither around the world guidance talk about particularly a discrepancy getting a danger indication [10, 11], even with relevant dangers for both mom and you may child, including preeclampsia otherwise low birthweight [thirteen, 18, 19].
