Answer;
-Amniocentesis
Celina underwent the process of amniocentesis.
Step-by-step explanation;
-Amniocentesis is a prenatal test in which a small amount of amniotic fluid is removed from the sac surrounding the fetus for testing. Amniocentesis is performed to look for certain types of birth defects, such as Down syndrome, a chromosomal abnormality.
-The sample of amniotic fluid (less than one ounce) is removed through a fine needle inserted into the uterus through the abdomen, under ultrasound guidance.
-The fluid is then sent to a laboratory for analysis. Different tests can be performed on a sample of amniotic fluid, depending on the genetic risk and indication for the test.
