Noninvasive prenatal genetic testing (NIPT) is revolutionizing the practice of obstetrics. However, the technol- ogy is expanding rapidly and in a way that has outpaced the rate at which evidence-based strategies for its in- tegration can be developed and implemented. Initially, NIPT was used as a screen for a limited number of an- euploidies and genetic conditions.

Prenatal genetic services have expanded at an extraordinary pace over the past 4 years with the development of fetal genome sequencing using cell-free placental DNA in maternal serum. Some commentators predict that this new technology, which allows for noninvasive determination of an increasingly wide range of maternal-fetal health conditions, will improve prenatal care, especially in lower-resource areas.

Recent expansions in prenatal genetic testing have renewed concerns from both disability advocates and right- to-life movements that these tests serve primarily to enable elective terminations, However, as prenatal genetic testing becomes easier, safer, and more accessible, many women say they choose it for a very different reason: preparation.

PROJECT NARRATIVE Preparation is often cited as a reason for offering and for accepting prenatal genetic screening and diagnosis. However, this term has no clear definition, and thus it is impossible either to prove benefit or to recommend best practices.

PROJECT NARRATIVE The goal of this study is to study the effect of an evidence-based communication tool to support patients? decision-making about noninvasive prenatal genetic testing, by focusing on the communication that takes place in the clinical encounter.
