If the situation is bad after amniocentesis, the result will be notified immediately after it comes out, usually within 1 week, and can be checked out first through cell phone SMS or APP software, or some will be notified by phone first and then notified to pick up the report card. Amniocentesis is generally used for prenatal diagnosis in patients with high risk of Down screening. It is performed under ultrasound guidance by passing a puncture needle through the uterus into the amniotic fluid, extracting the amniotic fluid for examination and culturing the cell chromosomes in the amniotic fluid, and the culture time is about 2 weeks. After the results come out, if there is any abnormality, the pregnant woman will be notified at the first time. After all, if the amniocentesis is abnormal, most of the fetuses cannot stay and need to be induced. The results of amniocentesis are usually notified in about 1-2 weeks. After the amniocentesis, you need to be patient and take rest to prevent infection or leakage of amniotic fluid.
