Rising autism prevalence and longer wait times delay autism diagnosis

According to the CDC, 1 in 36 children in the U.S. are diagnosed with autism spectrum disorder (ASD). Even though ASD can be clinically diagnosed as early as 16 months old, the average age of diagnosis is currently 4 years of age. A biological, diagnostic tool can further inform clinical judgment and substantially improve early identification.

Clarifi Autism Saliva Test

Breakthroughs in epigenetic research identify biomarkers to aid in autism diagnosis

Clarifi ASD is a biological tool to aid in the diagnosis of autism based on epigenetics and the microbiome. Clarifi ASD is not a genetic test. It is the product of scientific advancements in the area of epigenetics; the factors that influence how genes are turned on and off. Our peer-reviewed research discovered that certain RNA molecules that regulate genetic activity and reflect interactions between a patient and their environment are different in children.
