Down syndrome screening for gender

Patient's question:

Patient Age: Why did the doctor recommend me to have a Down syndrome screening when I was pregnant and doing tests, but I don't understand

Doctor's answer:

The Down syndrome screening is a test to assess the risk of a fetus developing Down syndrome. It is generally recommended for pregnant women in early pregnancy. Down syndrome, in simple terms, is a sporadic form of intellectual disability, and individuals with this condition often have other congenital diseases as well, which are incurable. Therefore, it is still advisable to undergo the test. In Changchun, you can get the test done at Jilai Hospital or the 461st Hospital. The Down syndrome screening primarily involves blood tests, and if necessary, an ultrasound examination may also be performed, which does not involve determining the gender of the baby.
Why do expectant parents now want to know if their baby is a boy or a girl? Boys and girls are both treasures, and these days, there is no longer the preference for sons over daughters. In fact, it would be wonderful to keep the surprise until the baby is born!
