Is it too early to do a fetal anomaly screening at 28 weeks?

Minor fetal malformation screening is a test method for pregnant women, and this test method also has its special significance for expectant mothers. The timing and content of minor fetal malformation screening are also issues that expectant mothers are very concerned about. So, when should the minor fetal abnormality screening be done? What does the minor fetal malformation screening contain? Next, the editor will explain it in detail for everyone.

When should minor fetal abnormalities be screened?

The main purpose of the minor fetal malformation screening is to check the maturity of the internal organs. The inspection time is between 28-32 weeks, to eliminate some developmental abnormalities that occur in the late pregnancy, to understand the fetal position, placental position and maturity, amniotic fluid, etc. It can also determine whether the fetus has umbilical cord entanglement, how many weeks it has been around the neck, and how tight it is.

Is it too early to do a fetal anomaly screening at 28 weeks?

It's not too long ago, because fetal malformation screening is usually performed in the 18th week of pregnancy, using a black and white B-ultrasound method. However, B-ultrasound for fetal abnormality screening is usually scheduled for the 24th week of pregnancy, mainly three-dimensional or logical B-ultrasound, which can more comprehensively detect the growth and development of the baby's organs. Because the baby's organs at this stage have gradually grown and developed, the amniotic fluid flow is normal, and the B-ultrasound examination results are relatively reliable.

What does the minor anomaly screening contain?

The first color Doppler ultrasound examination: at 6 to 8 weeks, mainly to eliminate or promptly deal with ectopic pregnancy (ectopic pregnancy) or abnormal pregnancy (hydatidiform mole, etc.), and to understand whether the test tube embryo is alive.

The second color Doppler ultrasound examination: at 11 to 14 weeks, it is mainly to accurately measure the fetal nt and combine it with the maternal blood cell test to assess the risk of chromosomal abnormalities in the fetus.

The third color Doppler ultrasound examination: at 18 to 24 weeks, it is mainly to systematically screen the baby's development and confirm the presence of major deformities in the fetus, including anencephaly, brain herniation, open spina bifida, damaged chest wall, protruding internal organs, single-chamber heart, and giant cartilage dysplasia.

The 4th and 5th ultrasounds: at 32 to 38 weeks, to eliminate some abnormalities in the development of the baby that appear in the late pregnancy, to understand the position of the fetus, the position and maturity of the placenta, the amount of amniotic fluid in the pregnant woman, etc. It can determine whether the fetus has umbilical cord entanglement, how many weeks it has been around the neck, and how tight it is. It can also grasp the blood condition of the fetal umbilical cord and assess the well-being of the fetus in the uterine cavity.
