Question
What is the purpose of an amniocentesis?
- a) Diagnose genetic abnormalities
- b) Treat chromosome abnormalities
- c) Count chromosomes
- d) Treat genetic abnormalities
Solution
The purpose of an amniocentesis is to diagnose genetic abnormalities. So, the correct answer is a) Diagnose genetic abnormalities.
Here are the steps of how an amniocentesis is performed:
- An ultrasound is used to locate the amniotic sac.
- A thin needle is inserted through the abdomen into the amniotic sac.
- A small amount of amniotic fluid is withdrawn, which contains fetal cells.
- The fluid is sent to a lab where the cells are examined for genetic abnormalities.
This procedure allows doctors to diagnose genetic disorders in the fetus early in pregnancy. However, it cannot treat chromosome or genetic abnormalities.
