Due to the significant impact of Down syndrome on every family, it can cause a lot of pressure on family members. Therefore, it is necessary for pregnant women to undergo Down syndrome screening during pregnancy. If possible, women still need to understand the basic knowledge about Down syndrome screening and know that Down syndrome screening can directly affect the birth rate of Down syndrome infants. So, why is Down syndrome screening called Down syndrome screening?
In 1866, British doctor John Langton Tang first published this disease at the research institute. In 1959, French geneticist Jerome Le Guin discovered that this disease was caused by the first non disjunction of chromosome 21. This is also the first human disease caused by chromosomal defects. In 1965, the World Health Organization officially named the disease Down syndrome.
Down syndrome screening is a testing method that extracts serum from pregnant women to detect their component content, and calculates the risk of disease based on the specific situation of the pregnant woman. Down syndrome screening can 'filter' babies with defects, and 15-20 weeks of pregnancy is a better period for Down syndrome screening. The cost is approximately 200 yuan
When a pregnant woman is pregnant, she will undergo regular physical examinations to check if the fetus is abnormal or normal. In addition to regular prenatal check ups, mothers also screen children with Down syndrome, mainly to detect whether the fetus has congenital defects, that is, whether the fetus has severe intellectual disability. So, when should Donald's screening be conducted for the health of the fetus?
It is recommended to have an examination at 15-20 weeks after pregnancy, preferably between 16 and 18 weeks, as the possibility of congenital intellectual disability in the uterus can be predicted through current stage examinations. The reason why Down syndrome screening is necessary is to avoid the occurrence of fetuses with congenital intellectual disability.
