Non‐invasive prenatal testing: clinical utility and ethical concerns about recent advances

To the Editor: Thomas and colleagues1 describe the ethical complexities that can arise in the use of noninvasive prenatal testing (NIPT) based on the detection of cellfree fetal DNA in the maternal circulation to screen for chromosomal and other genetic fetal conditions, especially if the clinical utility and implications of the testing are not well understood and explained. They indicate that “the current NIPT tests available are for specific chromosomal aneuploidy, extended panels of targeted conditions and low resolution whole genome sequencing”.
