Babies with Down syndrome, commonly known as \”Down syndrome babies\”, are the most common chromosomal abnormalities in my country at this stage. The main characteristics of \”Down syndrome\” are low IQ and a special face. So far, there is no effective preventive method or effective treatment for this disease in medicine. Only through prenatal screening and diagnosis can we detect it as early as possible, terminate the pregnancy, and avoid the birth of affected children.
Experts remind that the following seven types of couples belong to high-risk groups:
1. Pregnant women have a history of viral infections before and after pregnancy, such as influenza, rubella, etc.;
hint:
The \”Five Teratogens\” examination can be used to diagnose whether pregnant women are infected with the above-mentioned viruses. The \”Five Teratogens\” is the TORCH examination, including detection of Toxoplasma gondii, rubella virus, cytomegalovirus, and herpes simplex virus.
Inspection cost and time: TORCH inspection fee is about 100 yuan. The time for TORCH examination is around 3 months of pregnancy.
2. At the time of conception, one of the spouses has a chromosomal abnormality;
Doctors recommend that pregnant women over the age of 34 undergo \”amniocentesis\” to check whether the fetus has chromosomal abnormalities; pregnant women under the age of 34 can do \”blood screening\” to screen whether the fetus is at high risk for chromosomal abnormalities.
Test timing: Maternal blood screening and amniocentesis can only be performed after 15-20 weeks in the second trimester.
3. One of the parties is older;
Nowadays, many white-collar women will choose to get pregnant and have children after their careers are stable, but often when they want a child, they find that they cannot get pregnant.
4. Pregnant women take teratogenic drugs, such as tetracycline, before and after pregnancy;
5. One of the spouses has been working under a radioactive curtain or in a polluted environment for a long time;
6. Pregnant women with a history of habitual miscarriage, premature birth or stillbirth;
7. One spouse keeps pets for a long time.
Therefore, pregnant women should undergo relevant examinations around 3 months into pregnancy. This test only requires two milliliters of blood for testing and will not cause harm to pregnant women and fetuses. The screening results will indicate whether to \”continue the pregnancy\” or \”terminate the pregnancy.\”
