32-week ultrasound shows 2 weeks less than gestational age

Patient's question:

Onset date: 2010.4.10
Laboratory test results: Biparietal diameter 78mm, Head circumference 287mm, Abdominal circumference 248mm, Femur length 57mm, Placenta grade I, located on the anterior wall, Amniotic fluid index 63mm. Ultrasound suggests 30 weeks +.

Doctor's answer:

Medical Analysis: You had an ultrasound examination at 32 weeks of pregnancy and found that the fetus was two weeks smaller than the expected gestational age.
Guidance: Do not judge whether you have intrauterine growth restriction (IUGR) based on a single examination result.
It is recommended that you refer to previous examination results. If the fetus has always been of normal gestational size during previous checks, and this examination shows it is smaller than the gestational age, it is advisable to consider appropriate treatment to improve the fetus's blood supply, oxygenation, and nutrition.
