Hello doctor i am 25yrs old and i am 25 weeks pregnant, and my doctor said that my baby s all fetal biometry parameters fall between 5th and 25th percentile for gestational age and the baby s growth is normal. I don t understand this please give a advice for this.
Hi, Fetal biometric parameters are calculated by comparison with an international data for that particular gestational age. Some mothers who are small built are going to have smaller babies especially Asian women who are smaller built and have smaller babies compared to the Caucasian or African women. So a lot of things go into calling a fetal growth normal. Even so, any percentile between 5 and 95 we consider normal. It is less than 5th gentile that we worry about. So, by the report it looks like your baby is quite ok, and you need not worry. Hope this helps. Regards.
