My quad results showed I have a 1:454 of having a child with Down's Syndrome. Should I have an amniocentesis performed? I am currently living in China and my doctor recommended I get the amniocentesis but I am not sure I should since the risk for DS is so

Amnio has risks too. Only you can make a decision regarding your pregnancy, but how will the results of the test alter your decision to carry pregnancy to term? Will it affect you ability to bond with your unborn baby? Overall lifetime risk of DS is 1:800 but slightly less in women under 30 and significantly higher after age 40,, so your risk is still low. www.mayoclinic.org/tests-procedures/amniocentesis/basics/
