About Autism?

MAR-Autism, or maternal autoantibody-related autism (MARA) is due to antibodies made by a mother’s immune system that affect the baby’s developing brain. The MAR-Autism™ Test looks for these antibodies in mom’s blood and aids in the diagnosis of autism.

The autoantibody combinations associated with MAR-autism were detected. A positive result is associated with a greater than 97% risk of an autism diagnosis in a current or future biological child.

Circle with negative sign, indicating medical negativity.

Negative result

The autoantibody combinations associated with MAR-autism were absent. Your result indicates a low risk that current or future children would be affected by the MAR-autism subtype.

Frequently asked questions

Squigly Heart

  • The MAR-Autism Test can accelerate the diagnosis and initiation of intervention for children whose mothers test positive. Early intervention is known to significantly improve quality of life for individuals with autism. Preconception testing can be useful for women with a high likelihood of having an autistic child, allowing them to consider options like gestational surrogacy, adoption, or preparing for a child with an elevated likelihood of high support needs.

  • No. You can either request through your healthcare provider or request here using our telehealth partner.

  • You submit a request for testing to the telehealth provider. Once they approve your order, you sign into our patient portal, sign a consent, and make payment. We ship you a blood draw kit to the address you provided on your intake form, and work with you to schedule a blood draw at a lab location near you. After the draw, the phlebotomist will ship your specimen to our lab. You will receive your results in the patient portal within 14 days of the specimen receipt in our lab.

  • Yes. MARAbio offers a Financial Assistance Program for eligible patients who need help paying for the MAR-Autism Test. Eligibility is based on household size, annual household income, and other information submitted as part of the application process. More information can be found on our billing page.

  • MAR-Autism is a non-genetic cause of autism that is caused by the presence of specific autoantibody combinations present in the mother of an affected child. These maternal autoantibodies can cross the placenta and the fetal blood–brain barrier, disrupting neuronal development.  Early findings also link antibodies associated with MAR-Autism to higher ADOS scores and an increased likelihood of higher support needs.

  • Test results are completed within 14 days of our laboratory receiving your specimen. Your results will be available through our online portal.

  • The test is not covered by insurance at this time. You will receive a receipt for the test which provides the amount you have paid. You may be able to submit to your HSA/FSA, but we suggest you check with your HSA/FSA provider to determine eligibility requirements and coverage prior to submission.

  • We accept HSA/FSA, debit, or credit card payments in the portal during account set up. If you have issues with this, you can contact us at support@marabio.com.

Text reads 'I love you'. The phrase is complemented by a blue heart symbol.
