Risks

Prenatal cell-free DNA screening poses no physical risks for you or your baby.

While prenatal cell-free DNA screening might cause anxiety, it might help you avoid the need for more invasive tests, treatment or monitoring during your pregnancy.

Keep in mind, however, that prenatal cell-free DNA screening doesn't screen for all chromosomal or genetic conditions. A negative test result does not ensure an unaffected pregnancy.
