How long does it take for the umbilical cord puncture to produce results?

Umbilical cord puncture is the main method to check whether the fetus has chromosomal diseases and Down syndrome. It is diagnosed by checking the blood in the umbilical cord. It is usually a surgical method performed before delivery. The results of the examination usually take two weeks to get results. It is also a pregnancy test that every expectant mother must take, so pregnant women should follow the doctor's advice to do the umbilical cord puncture examination method.

How many days will the results of cord blood puncture be available?

Umbilical cord blood puncture is a type of prenatal check-up item. The umbilical cord blood test is to extract the umbilical cord blood through a needle puncture. It is used to diagnose whether the fetus has chromosomal diseases, especially trisomy 21 (Down syndrome) and trisomy 18. Experts recommend: Pregnant women over 35 years old need to undergo prenatal diagnosis to diagnose whether the fetus has chromosomal diseases.

Umbilical cord blood puncture is when the needle enters the abdomen and punctures the baby's umbilical vein under the guidance of B-ultrasound, and 3-5 ml of blood is drawn for culture and testing. The report will be issued in about two weeks. Umbilical cord blood puncture has a slightly higher risk than amniocentesis, but it is also more accurate than amniocentesis.

Umbilical cord blood puncture is a diagnostic method that can be performed at any time after 20 weeks of pregnancy, with 20-24 weeks of pregnancy being the best. There are currently three main types of biopsy techniques: chorionic villus sampling, amniocentesis, and cord blood sampling. Chorionic villus sampling is suitable for the diagnosis of Down syndrome and other chromosomal abnormalities in early pregnancy (11 weeks to 14 weeks). The diagnosis is made by obtaining placental tissue through puncture. Amniocentesis is suitable for prenatal diagnosis of abnormalities such as Down syndrome in cases between 16 and 24 weeks of pregnancy. Umbilical cord blood sampling is a diagnostic procedure that can be performed any time after 20 weeks of gestation.

So, how many days will it take for the results of umbilical cord blood puncture to come out? The cost of umbilical cord blood puncture varies from hospital to hospital, and is approximately 1,500-2,000 yuan, including the cost of blood drawing, laboratory tests, etc. The results will generally be available within 2-3 weeks. There are certain risks associated with cord blood puncture:

1. The decision is made based on the menstrual period. If the menstruation is irregular, the calculation result will be inaccurate. For irregular menstruation, the Down syndrome risk value is generally calculated based on the earliest ultrasound report.

2. After the umbilical cord is drawn, the bleeding cannot be effectively stopped. Once stimulated, there may be a risk of stillbirth or other miscarriage.

Experts suggest: The older the gestational age, the more important it is to use umbilical cord puncture. On the one hand, it can improve the diagnosis rate and reduce the chance of culture failure. On the other hand, the risk of miscarriage for children with a higher gestational age will be significantly reduced.
