Purpose We surveyed parents to ascertain interest in newborn genomic testing and determine whether these queries would provoke refusal of conventional newborn screening (NBS). Methods: After brief genetics orientation, parents rated their interest in receiving genomic testing for their healthy newborn on a 5-point Likert scale and answered questions about demographics and health history. We used logistic regression to explore factors associated with interest in genomic testing and tracked any subsequent rejection of NBS. Results: We queried 514 parents within 48 hours after birth while still in the hospital (mean age (sd) 32.7 (6.4) years, 65.2% female, 61.2% white, 79.3% married). Parents reported being not at all (6.4%), a little (10.9%), somewhat (36.6%), very (28.0%) or extremely (18.1%) interested in genomic testing for their newborns. None refused conventional NBS. Married participants and those with health concerns about their infant were less interested in newborn genomic testing (p=0.012 and p=0.030, respectively). Mothers’ and fathers’ degree of interest was discordant (≥ 2 categories different) in 24.4% of couples. Conclusions: Interest in newborn genomic testing was high among parents of healthy newborns and the majority of couples had similar levels of interest. Surveying parents about genomic sequencing did not prompt rejection of NBS.
