![]() ![]() Autism diagnosis timingĪrora and his team hope their technology could help young children, even newborns, receive early interventions for autism sooner than they can now. “We can detect the clear rhythm of autism with just about one centimeter of hair,” Arora said. That’s where a machine-learning algorithm takes over - it’s trained to look for patterns of dysregulation in metals that the researchers believe are biomarkers of autism. The technique creates huge amounts of data. “It’s almost like having a security camera where you can go back and get a look at four pictures a day,” Baccarelli said. LinusBio says its test can reveal metal metabolism in 4-6 hour increments. A centimeter - less than half an inch - of hair captures roughly a month’s worth of exposure data, Arora said.Īs a tree’s rings tell scientists about growing conditions each year, hair growth allows researchers to understand what was happening in someone’s body during specific moments in time. The test runs a laser along the length of a hair, using its energy to turn it into a plasma for analysis. The technology was developed from research completed at Mount Sinai.įor an infant, hair can provide a glimpse of the exposures in moments critical to development, like the third trimester of pregnancy. The LinusBio test analyzes the history of the metabolism, telling the story of what substances or toxins the child has been exposed to over time, according to Manish Arora, the company’s co-founder and CEO, who is also a professor of environmental medicine and public health at the Icahn School of Medicine at Mount Sinai, the academic arm of the Mount Sinai Health System. Scott Myers, a neurodevelopmental pediatrician at the Geisinger Autism & Developmental Medicine Institute, wrote in an email. “There is certainly much more work to be done before concluding that this test is a valid measure of autism spectrum disorder risk,” Dr. All agreed the findings should be replicated by other teams. Although many were excited about the potential of the underlying science, most said caution is warranted and that more research is needed. ![]() NBC News spoke to six independent experts from different scientific backgrounds about LinusBio’s test. ![]()
