USA: autism biomarkers show up in blood test

07 November 2018

Biomarkers can be detected in some children with autism spectrum disorder (ASD), which may lead to earlier diagnosis and even targeted dietary therapy.

Researchers, working with prior evidence that dysregulation of amino acids may contribute to ASD, tested whether this was a pervasive phenomenon.

They found that dysregulation of amino acid metabolism can be used to detect around 17% of children with ASD.

David Amaral, senior author of the study published in Biological Psychiatry, said: ‘We are currently looking at other metabolites that distinguish other subsets of children with autism.’
