About the NPDX AA test

What is the NPDX AA test?

The NPDX AA test is a new tool to help children and families affected by autism spectrum disorder (ASD). The test measures differences in the metabolism of children associated with an ASD diagnosis in our clinical study, the Children’s Autism Metabolome Project (CAMP).

A tool for earlier ASD diagnosis

Earlier diagnosis and intervention can help children with ASD thrive. Behavioral tests can lead to an ASD diagnosis in children as young as 24 months old, but the average age of diagnosis in the United States is more than 4 years! Our NPDX AA test can help kids receive a diagnosis and begin treatment sooner.

It can be difficult to know when to be concerned because kids develop different skills, like walking and talking, at different times. It can be hard to tell if a child is experiencing delayed development that could signal a condition like ASD or is simply developing at a different pace compared to his or her peers.

This is why a biological test, one that’s less susceptible to interpretation, could help doctors diagnose children with ASD at a younger age. The NPDX AA test was developed for children as young as 18 months old.

A test that detects metabolic imbalances linked to ASD

In our research of autism spectrum disorder (ASD) and metabolism, we found differences in the metabolic profiles of certain small molecules in the blood of children with ASD.

The NPDX AA test measures a number of molecules in the blood called metabolites and compares them to these metabolic profiles.

Our test looks for certain metabolic imbalances that have been identified through our clinical study to be associated with ASD. When we detect one or more imbalance(s), there is an increased risk that the child will receive an ASD diagnosis.*

The results of our metabolic test provide the ordering physician with information about the child’s metabolism.

In some instances, this information may be used to inform more precise treatment. Preliminary research suggests, for example, that adding or removing certain foods or supplements may be beneficial for some of these children.

NeuroPointDX is working on further studies to explore this.

A highly-accurate tool able to identify ~30% of children with ASD

The NPDX AA test can identify about 30% of children with autism spectrum disorder with an increased risk of an ASD diagnosis. This means that three in 10 kids with autism spectrum disorder could receive an earlier diagnosis, get interventions sooner, and potentially receive more precise treatment suggestions from their doctors, based on information about their own metabolism.

A new approach to thinking about ASD that has been rigorously validated in a large clinical study

Through our clinical study, the Children’s Autism Metabolome Project (CAMP), we found differences in the metabolic profiles of certain small molecules in the blood of children with ASD. Our research has identified a connection between metabolism and autism spectrum disorder.

Over 1,100 children enrolled in CAMP, which was conducted at eight clinical sites across the country. NeuroPointDX is grateful to the families who participated and all of the health care professionals who helped make this study a success.

The results of CAMP have been published in a peer-reviewed, highly-regarded journal, Biological Psychiatry.
