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 15 business days after the sample is received at the lab.
Results and next steps
The telehealth provider who ordered the test for the child will review the results with the caregiver and discuss their recommendations for next steps.
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).
