When is Amniocentesis typically performed?

Amniocentesis is typically performed between 15-20 weeks of pregnancy, which allows for the sampling of amniotic fluid to test for genetic abnormalities or other conditions. This timing is crucial as it provides a balance between the earliest possible diagnosis and minimizing risks to both the mother and the fetus. During this period, the fetus is adequately developed, and sufficient amniotic fluid is present, making it safer and more effective for testing. The procedure can also increase diagnostic accuracy as the gestational age allows better interpretation of results, including chromosomal analysis and risk assessment for certain genetic conditions.
