New Hair-Based Test Offers Early Insight to Rule Out Autism
July 8, 2025
Could a strand of hair reveal early signs of autism? This innovative test says yes with powerful implications.
The journey to understanding autism has taken a remarkable step forward with the introduction of a new, non-invasive test that analyzes just a single strand of hair to help rule out autism spectrum disorder in very young children. This innovative approach is now available to families in most states, offering a fresh option in the often complex and lengthy process of early autism evaluation.
Imagine a test that can provide clues about a child’s developmental health simply through the analysis of hair.
This is exactly what the Clearstrand-ASD test offers. Developed by a New Jersey-based startup, this test is designed for children between 1 and 36 months of age and aims to help physicians rule out autism, not diagnose it, but provide a biochemical aid that supplements traditional behavioral assessments.
The science behind this test is fascinating. Hair grows slowly, capturing a timeline of metabolic information much like tree rings tell the story of a tree’s environment over the years. By examining tiny segments of hair, researchers can identify patterns of exposure to metals and other substances, which some studies suggest could be linked to autism.
This gives doctors another tool to better understand a child’s developmental picture early on.
Early detection and intervention have long been recognized as critical in supporting children with autism. The sooner children receive the right therapies, the better their long-term outcomes. This new test, although not a definitive diagnosis, aims to speed up the process by ruling out autism in children who are at higher risk due to family history or early behavioral signs.

While the test is still new and undergoing further validation, early data shows promise. In one group of nearly 500 children at elevated risk for autism, the test could rule out autism with about 92.5% accuracy.
However, it's important to note that the test is currently not covered by insurance and costs around $2,750, making it a significant investment for families.
Parents or doctors can order the Clearstrand-ASD test through a telehealth appointment, where an independent physician provides the necessary prescription. The test kit is then sent to the home, and families simply send back a small hair sample.
Within about three weeks, the results are returned, offering additional insights that may help guide next steps in a child's developmental evaluation.
Though still early in its development and not FDA-approved, this hair-based test represents a hopeful addition to the landscape of autism evaluation tools. As research continues, it could help reduce the long wait times many families face when trying to get a clear answer about their child’s developmental needs.
