Patient's question:
Please ask if the FL value is small at 55.1mm during the 7th month of pregnancy ultrasound (other indicators are normal), whether it is possible for the fetus to be abnormal, and how to prevent it?Doctor's answer:
Hello: FL refers to the length of the thigh bone, also known as "femur length." The femur is the length from the hip to the knee. Generally, around the 20th week of pregnancy, FL is measured to check the baby's development. Based on your test results, it seems that the child is doing fine. At 28 weeks: femur length is 5.35 ± 0.55.
