Question
I am 29 years old and 19 weeks and 4 days pregnant, weighing 58.5 kilograms. The Down syndrome test report shows a critical risk of trisomy 21. I am asking whether I should undergo amniocentesis or non-invasive DNA testing.
Answer
When a Down syndrome test result indicates a high risk, options such as amniocentesis or non-invasive DNA testing can be chosen to determine if the fetus has Down syndrome. Amniocentesis involves extracting fetal cells from the amniotic fluid for chromosome testing, with potential risks including infection, amniotic fluid leakage, and miscarriage (approximately 1 in 1000 chance).
