During the pregnancy process, female friends need to undergo several ultrasound examinations, which is one of the most important examination items during pregnancy. Through ultrasound examination, the fetal development status can be determined, such as the presence of defects and deformities, and the baby's weight can be estimated. So, is the fetal weight estimation on the ultrasound sheet accurate?
The fetal weight estimation on the ultrasound sheet is not 100% accurate and may have some margin of error. Because this is only estimated by doctors based on the size of the fetus, not measured using a weight scale. So this weight can only be used as a reference and cannot be determined to be the actual weight of the fetus.
There are many methods to estimate fetal weight during pregnancy for female friends. In addition to ultrasound, the fetal weight can also be estimated based on the pregnant woman's uterine height and abdominal circumference. However, if the pregnant woman has a fuller figure, the fat layer in the abdomen will be thicker, which will increase the margin of error.
When conducting ultrasound examinations on pregnant women, doctors calculate their weight based on indicators such as fetal length and biparietal diameter. Although it cannot achieve 100% accuracy, it still has important reference significance. If it is found that the fetal weight is much lower than the standard, it is likely to be due to developmental problems. At this time, timely measures need to be taken, such as pregnant women supplementing more nutrients, which can help increase fetal weight.
