Your obstetric can also find out the gestational age via an ultrasound.
Ultrasounds can also give a relatively accurate estimation of gestational age using mathematical calculations known as fetal biometric measurements.
But, is also unreliable because they do not necessary coincide with the gestational age of the baby, some babies may be tiny or unusually big.
The following measurements of the fetus are taken:
- The fetal biparietal diameter (BPD),
- Head circumference (HC),
- Abdominal circumference (AC),
- Femur length (FL), humerus length (HL),
- And the crown rump length (CRL).
