What tests should be done at 28 weeks of pregnancy

What kind of examinations should be done at 28 weeks of pregnancy? This is a question that many people are very concerned about. Every parent hopes that their baby is healthy and smart. The examination at 28 weeks of pregnancy is also very important. During this period, a routine blood test should be done first. A four-dimensional color ultrasound examination is also very important. Imaging examinations can help detect whether the fetus has malformations, such as cleft lip, spina bifida, polydactyly, etc. Let’s take a closer look at what tests should be done at 28 weeks of pregnancy.

28-week gestational checkup items

In the 28th week of pregnancy, you have successfully entered the late stage of pregnancy. This week you will have your fifth prenatal check-up, and from this week on, the interval between prenatal check-ups will be changed to once every two weeks. Perhaps some pregnant mothers still don’t understand four-dimensional color ultrasound. This week, let’s take a look at this key examination item during pregnancy.

1. Routine prenatal examination items:

This week you will have your fifth prenatal check-up, which will include blood pressure, weight, uterine fundus height, abdominal circumference, fetal heart rate, obstetric B-ultrasound, blood routine and urine routine. These basic measurements can help doctors understand the basic condition of the expectant mother more comprehensively. Expectant mothers can also take this time to consult their doctors about any questions they want to know during pregnancy.

2. Key prenatal examination items: 4D color Doppler ultrasound

The necessity of doing four-dimensional color ultrasound: Color ultrasound can assist doctors in diagnosing congenital malformations of the fetus, including surface malformations and visceral malformations. For example, congenital heart disease, cleft lip and palate, hydrops fetus, polydactyly and external ear malformations can all be detected. At the same time, the exact position of the fetus in the uterus can be determined.

Interpretation of key prenatal examination items at 28 weeks of pregnancy

1. Four-dimensional color ultrasound examination method: Generally, the examination is conducted at 24-28 weeks of pregnancy. You need to make an appointment in advance and go to the hospital for examination on time to avoid missing the best time.

2. The contents of the four-dimensional color ultrasound examination: Not only can the growth process of the fetus be observed, but also the activities of the fetus in the mother's body can be intuitively seen, such as breathing, movement, including large movements of the whole body, movements of the limbs, and even the tiny swallowing movements of the fetus. Doctors can also use four-dimensional color ultrasound to observe whether the fetus has good tension. Normally, when the fetus is damaged by lack of oxygen in the uterus, the fetal activity will be significantly reduced or disappear, and it is difficult to detect these changes without an ultrasound examination.

Tips for prenatal check-up at 28 weeks of pregnancy

1. No need to hold urine

In terms of preparation for the four-dimensional color ultrasound, one difference between the four-dimensional color ultrasound and the general B-ultrasound examination is that before the examination, there is generally no need to prepare to hold urine. As long as the expectant mother goes to a regular hospital for examination within the four-dimensional color ultrasound examination time, fetal malformation screening and other examinations can be performed.

2. The sex of the fetus cannot be determined for non-medical purposes

Four-dimensional color ultrasound can detect the gender of the fetus, but expectant parents should be reminded that revealing the gender of the fetus for non-medical purposes is illegal according to national regulations, so regular hospitals will not tell or hint at the gender of the fetus in any way. In fact, whether it is a boy or a girl, they are the fruit of the love between husband and wife. Prospective parents should pay more attention to factors such as whether the fetus is healthy and whether its development is normal.

3. Four-dimensional color Doppler ultrasound cannot replace Down syndrome screening

Four-dimensional color ultrasound is an important means to rule out fetal appearance deformities, so as to achieve timely detection and correction. Four-dimensional color ultrasound can only clearly show the development of the fetal surface, but cannot check the fetal intelligence. Some children with Down syndrome do not have any physical defects at birth, but will gradually show intellectual disabilities during the development process. These are difficult to detect through four-dimensional color ultrasound, so it is necessary for expectant mothers not only to undergo a four-dimensional color ultrasound examination, but also to do Down syndrome screening.
