Down syndrome is a genetic condition which causes serious physical and developmental problems.
Individuals with this type of condition are born with extra chromosomes (chromosome 21).
Extra chromosomes lead to mental and physical issues.
Ultrasound can detect down syndrome only at the back of the fetus’s neck by the presence of fluid. Image testing can help in indicating the possibility of the syndrome.
Chorionic villus sampling, amniocentesis, and maternal serum studies are other tests to confirm Down syndrome.
