Autism Spectrum Disorder: Which Genetic Test Does Your Child Actually Need?

If you’ve discovered that autism can be linked to genetic factors, the next natural question is: “How can I find the specific cause for my child?” With various testing options available, choosing the right one can be overwhelming. This guide simplifies the clinical path to help you secure the most accurate diagnosis and better plan for your child’s future.

1. Why Genetic Testing is a Game-Changer for ASD

Genetic testing is more than just a diagnosis; it’s a roadmap for personalized care.

• Targeted Management: Identifying a specific genetic variant can reveal potential co-occurring medical conditions (e.g., epilepsy or metabolic issues).
• Ending the Diagnostic Odyssey: Many families spend years on inconclusive tests. Comprehensive sequencing can provide the “missing piece” much sooner.
• Future Family Planning: Understanding the inheritance pattern helps parents assess the likelihood of autism in future siblings.

2. Comparing Your Options: CMA vs. WES vs. WGS

Not all genetic tests are created equal. Understanding the “Diagnostic Yield” (the success rate of finding a diagnosis) is key.

3. The 3billion Advantage: We Never Stop Looking

Even the best tests can sometimes return an “inconclusive” result because genomic science evolves every day. This is where 3billion stands apart:

• Continuous Reanalysis: If your child remains undiagnosed, we don’t just stop. We reanalyze your data daily against the latest global research to find answers that didn’t exist yesterday.
• AI-Driven Precision: Our proprietary AI engine, EVIDENCE, accelerates the interpretation of complex variants with 99.9% accuracy.

4. Checklist: Is Your Child Ready for Advanced Testing?

If you answer “Yes” to any of the following, a comprehensive WES or WGS test is highly recommended:

• [ ] Has your child had a “normal” CMA or Fragile X test but still shows clear ASD symptoms?
• [ ] Are there additional symptoms like developmental delays, seizures, or unique physical features?
• [ ] Do you want the most definitive answer to avoid the stress of repetitive testing?
• [ ] Would you like to receive updated results as new genetic discoveries are made?

5. Take the Next Step for Your Child

Finding the right test is a vital step toward a clearer future. Our clinical team is here to help you navigate these options based on your child’s specific history and your location.
