OBJECTIVE: The aim of this study was to assess awareness, potential adoption, 
and current utilization of non-invasive prenatal testing (NIPT) analysis for 
common fetal aneuploidies among obstetricians.
METHODS: A 36-item web-based survey was designed to assess the current practice 
of fetal aneuploidy screening and knowledge and utilization of NIPT for fetal 
trisomy. Practicing obstetricians in the United States were invited via email to 
participate in the survey.
RESULTS: Of the 101 obstetricians that completed the survey (27% academic-based, 
73% private practice), 97% offer screening to high-risk patients and 91% offer 
screening to average-risk patients. With regard to current screening tests, the 
top three advantages were as follows: recommendation by professional societies, 
no risk to the pregnancy, and long history/experience with the test, whereas the 
top three limitations were as follows: patient anxiety, risks of follow-up 
invasive testing, and high false positives. NIPT had been used by 32% of 
respondents and 22% were familiar with NIPT and the associated clinical data. 
The majority of physicians predicted that they would offer NIPT to high-risk 
women (86.1%) and average-risk women (76.2%) within 12 months.
CONCLUSION: Obstetricians plan to increase their utilization of NIPT and expect 
that the majority of both high-risk and average-risk patients will be offered 
NIPT as an option.
