Test and See
ClearStrand-ASD is the first and only objective laboratory test that can help health care providers rule out autism in children less than 3 years of age, using a strand of hair.
Starting with just a strand of hair
Request the test
Have a telehealth provider assess if your child qualifies for ClearStrand-ASD, provide your payment information, and then the provider will place the order.
Provide hair sample
Collect a hair sample and return it to LinusBio's laboratory in the postage-paid collection box. The result will be ready within 3 weeks after the sample is received at the lab.
Results and next steps
After receiving the test result, ClearStrand-ASD patients are eligible for a full telehealth evaluation with an autism specialist at no extra cost.
About ClearStrand-ASD
Early identification of autism is important.
When autism is a concern, many caregivers may be left waiting and wondering if their child is on the autism spectrum. Autism-specific interventions initiated in the first 1 to 3 years of life are associated with improvements in IQ, language abilities, and social skills.
ClearStrand-ASD is a laboratory test ordered by a health care provider to help rule out autism spectrum disorder (ASD) when it is a concern in children aged 1 month up to 3 years. It has the potential to help caregivers plan the next steps for their child earlier than ever before.
Objective tests make a difference.
ClearStrand-ASD
is a noninvasive test that detects a biomarker associated with autism using a strand of hair.
The patterns of an individual’s biological response to certain elements can be measured in their hair and are different in autistic and non-autistic people. This is referred to as the “biomarker”.
ClearStrand-ASD analyzes hundreds of time points along a strand of hair and uses a validated algorithm to assess the likelihood of autism from the patterns. It is not a genetic test.
CLIA-Certified Laboratory
The test is performed by the LinusBio CLIA‐certified laboratory (CLIA# 31d2307499) in North Brunswick, NJ. It has not been cleared or approved by the US Food and Drug Administration (FDA).
Patented Robotic Technology and Laser Ablation Methods
ClearStrand-ASD uses patented robotics and laser ablation technology to release molecules from hair and map the patient's biological responses to elemental exposures. These metabolic signatures differ between autistic and non-autistic individuals.

-
ClearStrand-ASD is a first-of-its-kind test. It detects a biomarker associated with autism using a strand of hair.
How does the test work?
-
ClearStrand-ASD offers 2 possible results, a negative result or a non-negative result. ClearStrand-ASD testing does not provide a confirmation of autism. Children with the biomarker might not be diagnosed with autism when they are evaluated by a skilled professional.

Important information
ClearStrand-ASD is a biochemical test intended to help health care providers rule out autism spectrum disorder (ASD) when it is a concern in children aged 1 month up to 36 months of age. It detects a biomarker associated with autism using a strand of hair. ClearStrand-ASD must be ordered by a licensed health care provider. Rx only. ClearStrand-ASD results can be negative or non-negative.
A child with a negative result is unlikely to be on the autism spectrum. A child with a non-negative result may need further autism diagnostic evaluation. ClearStrand-ASD is not a standalone diagnostic test. Health care providers should consider the test result in the context of other factors relevant to their clinical decision making. ClearStrand-ASD analyzes a strand of hair to map the dynamic patterns of an individual's unique biological response to environmental exposures over time at a molecular level and uses an algorithm to assess the likelihood of autism from the patterns. It is not a genetic test.
The test is performed by the LinusBio CLIA-certified laboratory (CLIA #31d2307499) and has not been cleared or approved by the US Food and Drug Administration (FDA).
