Researchers at Arizona State University have developed a urine test that identifies microbially derived metabolites linked to autism spectrum disorder (ASD). This tool, which shows 90% sensitivity and 100% specificity, aims to enhance early diagnosis and support for children at risk of ASD, shifting the focus from behavioral to biological assessments.
- 01The urine test identifies 17 microbially derived metabolites (MDMs) that are significantly elevated in children with autism spectrum disorder (ASD).
- 02The Microbially-Derived Metabolite (MDM) System demonstrates 90% sensitivity and 100% specificity in classifying ASD in children aged 2-11.
- 03Up to 90% of ASD cases may be linked to gut microbiome imbalances, suggesting a biological basis for the disorder.
- 04The test is now available in the US and internationally, aiming to reduce diagnostic delays and improve early intervention.
- 05The research emphasizes the need for diagnostic tools that focus on biological markers rather than solely behavioral assessments.

Researchers from Arizona State University have introduced a urine-based screening tool that could revolutionize autism spectrum disorder (ASD) diagnosis by focusing on biological markers rather than solely behavioral assessments. The study involved 99 children aged 2 to 11, including 52 diagnosed with ASD. The team identified 17 microbially derived metabolites (MDMs) that were significantly elevated in ASD-affected children, with some metabolites showing levels up to 1,000 times higher than those in typically developing peers. The new Microbially-Derived Metabolite (MDM) System achieved 90% sensitivity and 100% specificity in classifying ASD cases. This advancement highlights the potential role of the gut microbiome in neurodevelopment and aims to facilitate earlier diagnosis and intervention. Researchers stress that the test is not a standalone diagnostic tool but a step towards understanding the biological underpinnings of ASD. The MDM test is now available in the US and internationally, with the hope of reducing stigma and encouraging parents to seek timely support for their children.
