Question
I am 23 years old and have no genetic history. Do I need to undergo an amniocentesis procedure? Is my risk of Down syndrome really high?
Answer
Down syndrome screening is not a diagnostic method but a risk assessment method. Although you do not have a family history of genetics, the screening results for Down syndrome show that your risk is indeed high, approximately 1 in 50. The cutoff for Down syndrome screening is 1 in 250, so for further confirmation, it is recommended that you undergo an amniocentesis. Down syndrome is a chromosomal abnormality that causes congenital intellectual disability. If the baby is diagnosed and born, it will bring a heavy burden to the family. Therefore, amniocentesis can provide an accurate diagnosis and help you make a reasonable decision.
