Umbilical cord blood sampling

I don’t know if all pregnant women have done umbilical cord blood puncture. It sounds scary. In fact, umbilical cord blood puncture can check the baby’s development, see whether the body is symmetrical, whether the genetic characteristics are stable, and it can also judge the physical condition of the expectant mother. This technology can also detect chromosomal abnormalities, fetal malformations and fetal maldevelopment.

Umbilical cord blood puncture is very common in prenatal examinations. Many women have done this examination, but most people around us have not done this examination. Sometimes we feel that it is unnecessary. Such an examination sounds scary. What exactly does it check?

Umbilical cord blood puncture is one of the important prenatal examinations. It plays an irreplaceable role in diagnosing the development and health status of the fetus in the womb. Umbilical cord blood puncture and amniocentesis chromosome testing can both check whether the fetal spine has any deformities. The location of umbilical cord puncture is determined by the position of the placenta. The part free in the amniotic fluid can be punctured, or the root of the umbilical cord on the fetal side or on the placental side can be punctured. Most people choose to puncture the umbilical vein. The method is basically the same as amniocentesis, except that the puncture site is different.

This is a procedure similar to acupuncture in the muscle. If you relax during the procedure, you will not feel any noticeable pain. At the same time, the operation generally requires to be performed by a doctor with experience and qualifications in prenatal diagnosis. The puncture operation itself is a minor operation with low risk, so there is no need to worry too much.

Umbilical cord blood is usually collected and centrifuged, and then: (1) the supernatant is taken for biochemical analysis to monitor fetal maturity or detect certain congenital malformations, especially neural tube defects such as anencephaly and hydrocephalus; (2) the cells are subjected to sex chromatin examination, chromosome analysis, and enzyme biochemical analysis to predict or determine the sex of the fetus, which helps diagnose genetic diseases with chromosomal abnormalities and congenital metabolic defects.

The principle of cord blood puncture is the same as that of amniocentesis, except that the puncture site is different. However, it requires a higher technical level of the doctor because the umbilical cord floats in the amniotic fluid. It must be performed by an experienced doctor, especially when performing intrauterine fetal blood transfusion, which requires a well-trained team of doctors to carry out.

Don't be too afraid of umbilical cord blood puncture. It can check the baby's development in all aspects and see whether the baby is healthy. It is the same as amniocentesis, but the puncture location is different. Female friends who want to do this examination should be prepared, especially mentally, and don't be too nervous.
