Amniocentesis is more expensive than the non-invasive DNA test, which is now cheaper and can be done for about$1,000. However, when you have a non-invasive DNA test, it is necessary to have an amniocentesis if there is an abnormality. Because there is still a certain amount of error in the non-invasive DNA test, it cannot be used as a final diagnosis or as a criterion for termination of pregnancy. Therefore, if there is a risk of abnormal fetal development, amniocentesis can be done directly. There are certain risks associated with amniocentesis, but the technology in our country is now more mature and the risk is very low.
