How long does it take for non-invasive results?

When I was screened by the doctor for Down's syndrome, a high-risk phenomenon appeared. The doctor said that I should do another non-invasive examination. How long does it take for the non-invasive results to come out?

Generally, the result of non-invasive surgery can be obtained in about one to two weeks, and the time to obtain the result has a certain relationship with the examination equipment in the hospital. If a low-risk result is found on a noninvasive test, it is normal and the pregnancy can continue. If a high-risk result is found during the examination, further amniocentesis is required. Once the fetal chromosomal abnormality is confirmed after the amniocentesis, the pregnancy must be terminated. During pregnancy, you need to be admitted to the hospital regularly for pregnancy tests to understand the development of the fetus in the uterus. At the same time, you should pay more attention to rest and avoid heavy physical labor.
