The American College of Obstetricians & Gynecologists (ACOG) and the Society for Maternal Fetal Medicine (SMFM) have issued new guidelines replacing previous guidance on prenatal genetic screening. The guidelines are restricted to subscribers and members. This post summarizes Practice Bulletin No. 226, offers brief commentary, and invites your thoughts on the new guidelines.

Are professional societies conflicted about cfDNA?
Prenatal cfDNA screening, often called NIPT, has given rise to many differences of opinion among professional societies. Recommendations about using cfDNA for prenatal screening have evolved slowly as studies have validated these tests – and, of course, as the tests themselves have changed and expanded over time. ACMG, representing medical genetics and laboratories, has tended to make the most expansive recommendations in favor of cfDNA screening, while ACOG, representing the bulk of obstetricians, has tended to be the most conservative group. Others, like ISPD, have usually fallen between the two extremes.
Commercial cfDNA labs, for their part, have grumbled about what they see as an overly slow pace of accepting this new technology (although, by historical medical standards, it’s actually been quite fast). One of their long-standing complaints has been revived in a just-published commentary in Prenatal Diagnosis. Adam Wolfberg, formerly employed by Ariosa (the makers of the Harmony™ cfDNA screen), argues in this new commentary that professional bodies have an inherent conflict of interest that has led them to resist more enthusiastic recommendation for prenatal cfDNA screening. Maternal-fetal medicine (MFM) specialists, he argues, see their livelihood endangered by this new technology, which threatens to undermine the fetal ultrasounds that are their bread and butter.

PIRC at ACOG 2017
Megan Allyse is representing PIRC at the 2017 annual meeting of the American Congress of Obstetrics and Gynecology (ACOG) in San Diego, with a poster presenting preliminary findings from the ERRORS (Errors in Reading and Reporting On Results of Screening) study. She presented the ERRORS poster, titled “Decisional Regret in Women Receiving High-risk or Inconclusive Results from Non-invasive Prenatal Genetic Screening,” in ePoster Session B on Saturday (Poster 24B).
She is also presenting a poster on ethical considerations in uterine transplantation surgery, in ePoster Session P on Tuesday (Poster 30P). Congratulations Megan!
ACOG Issues New Prenatal Testing Guidelines
The American College of Obstetricians & Gynecologists has issued new guidelines for prenatal diagnostic and screening testing for genetic disorders. These new guidelines will become the new rules by which obstetricians administer prenatal testing. Continue reading ACOG Issues New Prenatal Testing Guidelines
