Who is suitable for fetal umbilical cord blood flow examination?

What every woman worries about most after becoming pregnant is the health of the fetus. However, sometimes some conditions of the fetus cannot be detected through B-ultrasound and blood tests. This requires a fetal umbilical cord blood flow test to make a judgment. However, due to our lack of medical common sense, we don’t know whether everyone should do this test. Let’s take a look at which groups of people are suitable for the fetal umbilical cord blood flow test.

The purpose of checking the umbilical cord blood flow is to determine the development of the fetus in the uterus, such as whether there is intrauterine growth retardation, whether there is a tendency to develop pregnancy-induced hypertension syndrome, and whether there is intrauterine fetal hypoxia. Umbilical cord blood flow may sometimes show abnormalities due to fetal chromosomal abnormalities, congenital malformations, etc. Abnormal umbilical cord blood flow may also be related to developmental defects and histological abnormalities of the placenta. The normal value is related to the number of weeks of pregnancy. There are three main items, with the S/D value as the main indicator. The normal value is usually an S/D value of less than or equal to 3.0 in the late pregnancy.

Elderly pregnant women should have umbilical cord blood tests before delivery

There are certain risks in cord blood testing, so there are strict indications for testing cord blood during pregnancy. But for older pregnant women, this examination is best done. This method can detect whether the fetus has chromosomal abnormalities and hereditary blood diseases.

Older pregnant women are classified as high-risk pregnant women, one of the reasons being that the incidence of fetal malformations is higher than that of younger pregnant women. Due to the aging of spindle fibers in the egg cells of older women, unequal divisions often occur during mitosis, leading to chromosomal abnormalities in the daughter cells. This situation is more likely to occur when stimulated by adverse external factors. The result of chromosomal aberration can cause fetal malformation in mild cases and early miscarriage or stillbirth in severe cases.

In order to avoid this unfortunate incident, it must be discovered in time before delivery. Currently, many hospitals are able to perform umbilical cord blood tests on older pregnant women, which rarely poses a risk to the mother and fetus. For the sake of eugenics, it is better for older mothers to have an umbilical cord blood test.

The above is an introduction to the groups of people for whom the fetal umbilical cord blood flow test is suitable. After understanding it, we know that generally older pregnant women must do a good job of prenatal examinations, especially fetal umbilical cord blood flow examinations, so that they can better judge the situation of the fetus in the belly. In addition, you must maintain a happy mood during pregnancy, and eat more light and nutritious foods.
