Genetic testing, which has expanded in recent times with advances in expertise and the event of shopper merchandise, is on a path to widespread acceptance within the U.S., researchers at UT Southwestern Medical Middle discovered. The recognition of ancestry analysis and rising numbers of medical referrals are serving to drive that pattern, based on the examine revealed in Frontiers in Genetics.
“Genetic testing is an increasingly valuable tool for identifying a wide range of medical risks, including cancer, heart disease, neurogenetic conditions, prenatal diagnoses, and more,” mentioned examine chief Sukh Makhnoon, Ph.D., Assistant Professor within the Peter O’Donnell Jr. College of Public Well being and the Harold C. Simmons Complete Most cancers Middle at UT Southwestern.
“While the portfolio of accurate, affordable tests has expanded in recent years, growth in awareness among both individuals and the medical community has been incremental. Our study demonstrates that genetic testing may finally be reaching mainstream acceptance.”
Utilizing information from the 2022 Well being Data Nationwide Developments Survey, UTSW researchers discovered that 81% of Individuals are conscious of genetic testing and 40% have undergone at the very least one take a look at, up from 75% consciousness and 19% utilization in 2020.
Amongst 6,252 respondents, consciousness was highest for ancestry testing (72%), adopted by testing for particular illnesses (55%), prenatal genetic service testing (37%), and private trait testing (25%). Of the 4,403 respondents who answered the query on whether or not they had used a take a look at, ancestry assessments (23%) had been most typical, forward of particular illness danger (16%), prenatal service (8%), and private trait (6%).
Researchers additionally discovered that racial and ethnic disparities in using genetic assessments are narrowing, additional suggesting improved acceptance. For instance, Black (37%) and Asian (29%) respondents had been nearly as doubtless as white contributors (39%) to have undergone at the very least one genetic take a look at.
The involvement of genetic counselors, nonetheless, stays restricted. Solely 10% of all medical genetic assessments had been ordered by genetic counselors, who’re educated to supply related data and help to sufferers. Two-thirds of illness assessments, which require the involvement of a well being care skilled, had been ordered by physicians aside from genetic counselors.
“While those providers obviously recognize the benefits of testing, they may not have the training to successfully help patients understand and adapt to the medical or psychosocial consequences of genetic information,” Dr. Makhnoon mentioned.
“Our findings suggest that the medical community should emphasize the importance of continued genetic education for health care providers to strengthen their skills in supporting patients before and after testing—and better manage ongoing care once results are known.”
The examine builds on the rising physique of analysis associated to public well being genetics and its advantages in figuring out illness danger.
“This is a fairly new field of research, but one that is growing rapidly in importance due to technological advancements and the possibility of unlocking new pathways to patient care,” Dr. Makhnoon mentioned. “We are committed to continuing our efforts to enhancing the understanding of genetics through future research.”
