Most screening for LGA and macrosomia occurs during prenatal check-ups, where both fundal height and ultrasound scans can give an approximate measurement of the baby's proportions. [38] Two-dimensional ultrasound can be used to screen for macrosomia and LGA but estimations are generally not precise at any gestational age until birth. [36]
The Ballard Maturational Assessment, Ballard Score, or Ballard Scale, is a commonly used technique of gestational age assessment. It was devised by Dr Jeanne L. Ballard, professor emeritus of Pediatrics, Obstetrics and Gynecology at the University of Cincinnati College of Medicine.

Here's the formula to calculate your Estimated Due Date using Naegele's rule : Date of Last Menstrual Period + 7 Days + 9 Calendar Months = Date of Estimated Date of Delivery. Example: LMP = 8 May 2020 +1 year = 8 May 2021 −3 months = 8 February 2021 +7 days = 15 February 2021
Baby weighed as appropriate for gestational age. Birth weight is the body weight of a baby at their birth. [1] The average birth weight in babies of European and African descent is 3.5 kilograms (7.7 lb), with the normative range between 2.5 and 4.0 kilograms (5.5 and 8.8 lb). [2] On average, babies of Asian descent weigh about 3.25 kilograms ...
An ultrasound showing an embryo measured to have a crown-rump length of 1.67 cm and estimated to have a gestational age of 8 weeks and 1 day. Crown-rump length (CRL) is the measurement of the length of human embryos and fetuses from the top of the head (crown) to the bottom of the buttocks (rump).
It is rare for a baby weighing less than 500 g (17.6 ounces) to survive. [13] A baby's chances for survival increases 3–4% per day between 23 and 24 weeks of gestation and about 2–3% per day between 24 and 26 weeks of gestation. After 26 weeks the rate of survival increases at a much slower rate because survival is high already. [15]
