Having an amniocentesis, will Down syndrome be cured?

Patient's question:

Go for an amniocentesis, will Down syndrome be cured? The result is 1:150

Doctor's answer:

Analysis of the condition: Hello, whether to proceed or not is a decision you need to make yourself. However, it's important to understand these points first. The first is that the Down syndrome screening is a probabilistic test: the high-risk group only means the fetus is more likely to be a Down syndrome child, and there is still a possibility in the low-risk group. When the blood screening value is greater than 1/270, it is considered a high-risk group. The normal value is around 1/700. The international standard is 1/270. Additionally, the Down syndrome screening value is a corrected value. The main factors affecting the Down syndrome screening value include: the mother's age, gestational age, the fetal alpha-fetoprotein secreted by the fetus, the human chorionic gonadotropin secreted by the placenta, drug factors, genetic factors, etc. Taking "Dolima" for fetal preservation may cause human chorionic gonadotropin to exceed the normal value, which may affect the Down syndrome screening value.
Recommendation: Currently, the only medical method to determine if the fetus is a Down syndrome child is through amniocentesis. Amniocentesis involves extracting amniotic fluid, culturing fetal cells that have fallen into the amniotic fluid, and examining the chromosomes of the cells (specifically the 21st chromosome of the fetus).
Amniotic fluid extraction: 20ml of amniotic fluid is taken. The risks include possible infection, amniotic fluid leakage, and miscarriage. The probability of miscarriage is 1/1000.
