Hair Tests for Autism Screening

Tests designed to identify biomarkers associated with autism in infants and young children are open to the public in most states.

New Jersey startup Linusbio began testing on Thursday called Clearstrand-ASD. This test requires only one strand of hair.

This test is neither designed to diagnose autism spectrum disorder nor to be used alone. Instead, it aims to help doctors rule out autism in children, which is likely to be the case. This may be because the child has a sibling with autism or demonstrated behaviors related to the disorder.

Manish Arora, co-founder of Linusbio and its CEO, said Clearstrand-ASD is the only biochemical test available to detect autism spectrum disorder in children under 18 months of age. He hopes it will make the process of eliminating autism more efficiently and reduce the waiting time for those who need intervention or treatment the most.

“The focus is really on early intervention,” Alora said. “The sooner you intervene, the better your kids will.”

This test uses children’s hair to analyze the history of metabolism. Metabolic history tells the story of substances or toxins that have been exposed or processed over time, Arora previously told NBC News. His research has identified patterns of Metal exposure or metabolism dysregulation Some evidence suggests that it may be related to autism. Hair can provide a kind of timeline of what is happening in a child’s body, including patterns of metal exposure at certain stages of development.

“We can detect a clear rhythm of autism with about a centimeter of hair,” Arora previously told NBC News, and what the environment was like during a certain period of growth when a wooden ring was growing. We compared the dynamics and ways in which the story can be told.

The Food and Drug Administration has not approved the Clearstrand ASD test. However, as of Thursday, it is available to consumers in 44 states. If only I could pay $2,750.

This sets up the appointments of the independent physicians and telehealth that it offers, Arora said.

“You come to us, you get a prescription from an independent clinician. We’ll send you a kit. You’ll get results within about three weeks,” he said.

Diagnostic aid is still in the early stages of development, with limited data supporting its effectiveness. On Thursday, Linusbio shared several new first findings at the Metabolomics and Human Health Conference in Ventura, California. In a group of 490 children in California, who are at high risk for autism spectrum disorder, the test was able to eliminate it with an accuracy of around 92.5%, the company said. However, the results are not published in peer-reviewed journals.

2022 study on the company’s methodologyWe analyzed another Linusbio test published in the Journal of Clinical Medicine and found that it was still under development and that the methodology accurately predicts autism diagnosis (positive and negative) about 81% of the time .

The test is one of several promising ideas researchers are pursuing as a way to identify or exclude autism early in their children’s lives. Other scientists are considering eye tracking, blood tests and audio analysis as possible methods.

ClearStrand-ASD works by running the laser on the length of the hair being tested, turning the hair into a plasma that can be processed with machine learning algorithms. The results of the full analysis are expected within 3 weeks, after which the parents of the child participate in the follow-up telehealth appointment.

External experts said that while Linusbio’s hair strand test is promising, more research is needed.

“For me, this feels like it’s not the earliest, it’s on the early side of things.

Schenkop said: “This seems like an approach that could become part of a set of ways children can be screened for concern, but it’s more. It’s at the stage where you need evidence of that.

Sheinkopf works closely with primary care physicians who are concerned about the possibility of autism by families with young children who are careful to monitor their development and screen for autism. It suggested that there was.

“Sometimes, I see new shiny tools. I want to skip what’s already available,” he said.

Sheinkopf also noted parents who have evidence of differences in child development You can seek federally mandated services without a formal diagnosis.

Seeking a diagnosis of autism in a child can take a long time. American Academy of Pediatrics Autism screening is recommended at 18 and 24 months. Neurological tests, language assessment, behavioral observation, and other methods are ultimately used to diagnose children.

By helping to rule out autism in some children, Arora has given priority to the attention of those most needy, and wait times for families seeking care and treatment. He said he hopes it can be shortened.

Rebeccaranda, executive director of the Center for Autism Services, Science and Innovation at Kennedy Krieger Institute, a Baltimore pediatric care center focused on developmental disorders, has a shortage of experts to help diagnose and treat autism. He said he is doing it. That’s why she hopes that the test will make the child’s flow to professionals more efficient.

“It can accelerate the speed at which children are seen, and like that, children with very low chances of autism sit in a pipeline waiting to meet some kind of expert. Not,” she said.
