Abstract:
Aim: To understand awareness, knowledge and preferences regarding genetic testing among the USA general public. Methods: A cross-sectional online survey using a Qualtrics Panel. Results: Among 1600 respondents, 545 (34%) were White, 411 (26%) Black, 412 (26%) Hispanic or Latin(x) and 232 (15%) Asian. Most had heard of ancestry testing (87%) and genetic health risk testing (69%), but a third thought inherited genes were only a little or not at all responsible for obesity (36%) and mental health (33%). The majority preferred pre-emptive pharmacogenetic testing (n = 74%) compared with reactive testing. Statistically significant differences between racial/ethnic groups and rural-urban respondents were observed. Conclusion: Most preferred pre-emptive pharmacogenetic testing; however, about one-quarter preferred reactive testing. Preferences should be discussed during patient-clinician interactions.
