Which statement best describes invasive diagnostic testing during pregnancy?

It is non-invasive and risk-free

It is optional and risk-free

It is invasive and carries a small risk of miscarriage

Invasive diagnostic testing involves obtaining fetal tissue or cells by penetrating the uterus to analyze the fetus directly. Because it requires crossing the uterine barrier, there is a small but real risk of miscarriage (along with other procedure-related risks). It is not non-invasive, not risk-free, and it is not something performed after birth. Invasive tests are used when definitive genetic information is needed or when screening results indicate higher risk. This is why describing invasive testing as invasive and carrying a small risk of miscarriage best captures its nature.

It is only performed after birth
