Can I eat before having amniocentesis chromosome testing?

Patient's question:

No symptoms, initial check shows fetal brain problem

Doctor's answer:

Medical Analysis: Hello, amniocentesis is a procedure where amniotic fluid is extracted to test the epithelial cells that the child has shed for analysis.
Medical Advice: The child's chromosomes are determined when the fertilized egg forms, and this has nothing to do with whether the mother eats or not. However, if other blood tests are still needed, it is best not to eat before the procedure. You can bring food and have the pregnant woman eat after the test is completed.
