Bách phân vị cân nặng thai nhi (EFW) theo tuần
Nhập tuần thai và cân nặng thai nhi ước tính (EFW) để ước tính bách phân vị, xem khoảng thông thường từ bách phân vị thứ 10 đến 90 và nhãn đơn giản nhỏ/thông thường/lớn so với tuổi thai. Chỉ mang tính thông tin.
What is this fetal weight percentile tool for?
It gives a quick estimated percentile for a single EFW value at a given gestational week, plus a typical 10th–90th range.
Which weeks can I use it for?
Weeks 20 to 42.
What does “Small for dates” or “Large for dates” mean here?
It is based on this model only: below 10th = small, 10th–90th = typical, above 90th = large.
Does “Typical range” mean everything is fine?
Not necessarily. A single number can’t replace clinical interpretation or trend over time.
Can I use weights from different scans?
Enter the week and EFW from the **same scan** — don’t mix a week from one appointment with a weight from another. To follow growth, check each scan on its own and compare the results over time; trends across scans are more meaningful than one number, and your care team interprets them.
Does this replace my hospital’s growth charts?
No. Different clinics use different reference charts and ultrasound methods.
Is my data stored or shared?
This tool is intended for quick reference. Avoid entering identifiable personal info.
