Autism Detected Early via Urine Test
3 Jun
Summary
- A urine test identified 90% of autistic children accurately.
- Gut microbe metabolites in urine may signal autism risk.
- Early detection aids faster parental support and intervention.
Researchers have developed a novel urine test that shows promise in identifying children with autism spectrum disorder at an earlier stage than current observational tools. The test is based on the discovery that autistic children often exhibit distinct gut microbe profiles, which produce altered levels of key neurotransmitter metabolites.
Published in Molecular Psychiatry on May 26, 2026, the study found that these urine metabolite levels could distinguish autistic children from their neurotypical peers with 90% accuracy, without misidentifying any typically developing children. Significantly elevated levels of certain metabolites, linked to serotonin and dopamine pathways, were observed in nearly all autistic children.
This biology-based approach could alleviate parental anxiety and diagnostic hesitancy, as it points to a biological origin for autism. Early identification through this urine test is anticipated to facilitate quicker access to support and interventions, potentially improving outcomes for affected children.
Beyond diagnosis, the findings suggest potential therapeutic targets. Researchers noted that therapies aimed at influencing gut microbes might help manage these metabolite levels, contributing to healthier and happier lives for children with autism. Further testing is ongoing to validate the test's effectiveness.
