MARAbio Testing

Understanding One Pathway to Autism

Autism spectrum disorder has many contributing factors, and researchers continue to identify different pathways that can lead to its development. MARAbio testing represents one piece of this complex puzzle—a blood test that can detect specific maternal autoantibodies associated with autism risk.

What is MARA?

Maternal Autoantibody Related Autism (MARA) occurs when certain autoantibodies in a mother’s blood interfere with fetal brain development during pregnancy. While autism has multiple causes—genetic, environmental, and developmental—MARA appears to be a singular pathway that research suggests may account for approximately 20% of autism cases.

Studies indicate that when these specific autoantibodies are present, they predict autism development with over 95% accuracy, making this one of the most reliable biological markers identified in autism research.

About MARAbio Testing

MARAbio is currently the only clinically available test for detecting these autoantibodies. The test involves a simple blood draw and can be performed before conception, during pregnancy, or after an autism diagnosis to better understand contributing factors.

Who Might Consider Testing

Families with a child on the autism spectrum: Testing can help determine if maternal autoantibodies played a role in your child’s development and inform decisions about future pregnancies.

Women planning pregnancy: Testing before conception can identify this particular risk factor, though it’s important to remember that most autism cases stem from other causes entirely.

Understanding Your Results

Since autism has many different origins, a negative MARAbio result doesn’t eliminate autism risk—it simply rules out this specific pathway. Similarly, while a positive result indicates increased risk through this particular mechanism, it doesn’t guarantee autism will occur.

Comprehensive Support

At Wholesome Brain Medicine, we view testing as part of a broader approach to understanding neurodevelopment. If maternal autoantibodies are detected, we work with families on evidence-based strategies for immune system support and early intervention planning.

Our team recognizes that each family’s situation is unique, and we’re committed to helping you understand how this information fits into your family’s broader health picture.

We came to Wholesome Brain Medicine in hopes of understanding our 6 year old son’s struggle with anxiety and behavioral challenges. Through the use of Intellxx, we discovered some of the root causes affecting his behavior that we had never discovered through various other forms of testing.

Intellxx really was like finding a few essential pieces to a puzzle we’d been working on for 3 years! We were able to put him on a few supplements that are supporting him in the areas where he needed support! It was a really essential piece of the puzzle for us. If you’re already doing other testing, it’s a NO BRAINER to include genetic testing to get the full picture.

My Autistic son had a great deal of GI related issues, and Dr. Joy was able to help us navigate all his food sensitivities and work to heal his gut. Not only did many of his skin related issues resolve, but many of his “stims” improved or resolved too. He’s a much happier and healthier child now, and this has allowed him to continue to develop, learn, and grow.
