Abstract Chromosomal microarray analysis (CMA) is currently the first-tier diagnostic test recommended for children with undiagnosed intellectual disabilities. Long ordered by geneticists, CMAs are now increasingly being ordered by non-geneticist providers. This study explores parents’ understanding and emotions during the process of ordering CMA by geneticists and non-geneticists, and parents’ subsequent ability to derive utility from results. Twenty-two parents of children who underwent CMA testing participated in semi-structured interviews oriented around the domains of parental understanding, perceived utility, and affective response. Transcribed interviews were analyzed using inductive and deductive coding. Themes were explored for patterns, similarities, and differences between geneticist versus non-geneticist providers, as well as among those who received positive, negative, or variant of uncertain clinical significance (VUCS) results. We found that all parents of children with VUCS or pathogenic results received post-test counseling, but no parents of children with normal CMA results received post-test counseling. Nearly all parents reported that written resources and advice about online research was valuable, and this support was more likely to have been offered by genetics providers such as geneticists and genetic counselors rather than non-geneticist providers. Parents’ perceived utility of CMA results included having an answer or name for their child’s condition, providing information about reproductive risks and options, shaping expectations for the future, guiding their child’s medical management, and helping parents explain the condition to others. Emotions expressed by parents in relation to genetic testing included anxiety, frustration, guilt, relief, and hope. Nearly all parents reported anxiety while waiting for test results. Frustration was mostly expressed in relation to communicating with providers, particularly in trying to obtain their child’s test results. The results from this study provide important insights into parental experiences with CMA testing, and highlight the ongoing need for providers from all disciplines to be aware of challenges including communication issues and the presence of strong emotions during the genetic testing process.
