Children’s Autism Metabolome Project (CAMP)

The Children’s Autism Metabolome Project (CAMP) was the largest study to date to evaluate the metabolism of children with autism spectrum disorder (ASD).

  • 1,100 children enrolled
  • 18-48 months old
  • 8 clinical study sites, including some of the leading autism centers in the country
  • Consisted of behavioral evaluation and a fasting blood plasma sample.
  • Compared the metabolic results to the behavioral evaluation to identify differences in metabolism of children who were diagnosed with ASD.
  • Validated the NPDX ASD test, a tool that may lead to an earlier autism spectrum disorder diagnosis for some children

We are grateful to all of the children and families who participated in the CAMP clinical study. They took the time and trouble to help us better understand ASD and develop the NPDX ASD test, which has the potential to help kids receive an earlier ASD diagnosis and more precise treatment. Thank you!

CAMP was our largest study of ASD and metabolism, but it wasn’t the only research we conducted.
