The Down screening test in pregnancy is mainly an important method to screen for congenital genetic disorders in the fetus and to deal with any abnormalities as early as possible.
Down’s syndrome screening, referred to as Down screening, is usually performed by drawing fasting blood at 15-20 weeks of gestation. The main purpose of the test is to screen for the risk of fetal congenital genetic disorders, such as trisomy 21, trisomy 18, and neural tube malformations.
If it suggests low risk, it proves that the fetus is not a big problem. If it suggests medium-high risk, further non-invasive DNA, amniocentesis, cordocentesis, etc. are needed to further confirm the diagnosis.
It is recommended that patients undergo regular checkups to detect abnormalities in time and receive regular treatment as soon as possible under the guidance of doctors to minimize the adverse effects of the disease.
