Down syndrome can be detected by various prenatal screening tests during the first trimester of pregnancy, including ultrasound and maternal blood tests. It can also be diagnosed through genetic testing such as amniocentesis or chorionic villus sampling. It is not typically diagnosed at birth, although physical characteristics may suggest Down syndrome. Ages 1-2 or adolescence are also not typically when Down syndrome is diagnosed.
