Comparing genetic counselor’s and patient’s perceptions of needs in prenatal chromosomal microarray testing

OBJECTIVE Chromosome microarray analysis (CMA) is poised to take a significant place in the prenatal setting given its increased yield over standard karyotyping, but concerns regarding ethical and counseling challenges remain, especially associated with the risk of uncertain and incidental findings. Guidelines recommend patients receiving prenatal screening undergo genetic counseling prior to testing, but little is known about women’s specific pre- and post-testing informational needs, as well as their preference for return of various types of results.
