Abstract

Increasing interest and pursuit of genetic testing by the general public have raised concerns about their understanding and use of their results. While most research has focused on individuals receiving positive genetic test results, there have been limited investigations assessing the understanding and utility of receiving negative genetic test results. Individuals who receive a negative (or uninformative) genetic test result may not appreciate the limitations of genetic testing and their residual disease risk. The goals of this study were to explore participant understanding and perceived utility of negative non-diagnostic genetic test results. We conducted semi-structured interviews with participants who received negative non-diagnostic genetic test results from the electronic Medical Records and Genomics Network (eMERGE) testing panel at Northwestern University. A total of 17 participants were interviewed. While many expressed a lack of understanding of genetics and the relationship between genes, disease, and environment, most acknowledged that they had residual risk to develop a health problem and should continue with their routine health management. Additionally, participants expressed that their negative results had personal value, by providing them peace of mind and learning additional knowledge about themselves and their health. Participants did not anticipate that results would have an impact on their lifestyle, but felt the results were useful for sharing with their physician and could inform future genetic testing decisions. While mostly positive, some participants were disappointed not to learn more individualized results. While a more thorough exploration is necessary, findings in this study can aid efforts to improve or innovate informed consent for genomic testing, as well as scalable modes of result return that foster comprehension following negative genetic testing.
