Breakthrough autism test that detects risk in babies using a single strand of hair is approved in US

Scientists have announced a first-of-its-kind diagnostic test for autism spectrum disorder (ASD) that only requires a single strand of hair. LinusBio, based in New Jersey, launched its Clearstrand-ASD Thursday to help physicians rule out the condition in children between one and 36 months of age when autism is a concern. It does not provide a diagnosis. 'The test is intended for infants and toddlers who are at an elevated risk of autism, such as those who were born preterm, who have a sibling with autism, or who have demonstrated characteristics associated with autism,' researchers said. While Clearstrand-ASD only rules out autism, doctors currently rely on observational signs that leave parents waiting for answers.
