Urine Test Detects 90% of Autistic Children

5/27/2026

Summary

Researchers Develop Urine Test

Researchers created a urine test that flagged 90% of autistic children in a pilot.
The study enrolled 52 autistic and 47 typical children aged 2-11.
In the scan, 45 of 50 autistic participants showed elevated gut chemicals, none of the healthy did.
A confirmation phase later achieved 78% accuracy with no false-positive results.
Authors suggest the biomarkers define a new autism subtype covering roughly 90% of cases.

Summary

Autism Lab Certified

The Autism Diagnostics Laboratory earned CLIA certification to offer a urine autism test in the United States in 2026.
Analutos in the United Kingdom now supplies the assay internationally via a partnership.
The test is promoted as a triage tool to prioritize referrals.
The assay was developed through a collaboration among Arizona State University, Harvard Medical School, Rensselaer Polytechnic Institute and sites in Tennessee and Texas, and is now being commercialized.

Summary

Researchers Launch Test

Researchers introduced ASD-MDM, a phenotype covering 90% of autistic children with microbial metabolites.
The remaining ~10% showed metabolic anomalies suggesting rare inherited disorders.
Analutos in the United Kingdom now sells the urine test internationally.
Rosa Krajmalnik-Brown said the assay makes the gut-autism hypothesis actionable in clinics.
Researchers said only controlled trials proving benefit from lowering metabolites will justify therapies, despite an open-label study that lowered p-cresol sulfate and improved symptoms.
