More about testing

How Does Testing For CTX Work?

If approved for a no-cost genetic testing program, you'll receive a clinical-grade test kit delivered right to your door, offering both convenience and accuracy. Simply provide a saliva or cheek swab sample, and our advanced technology will handle the rest, revealing valuable genetic insights. The testing offered is whole exome sequencing, and it will not only test for the gene associated with CTX. It’s our goal to do our best to uncover an answer for your symptoms by providing broad and comprehensive testing.

  • Physician-ordered, with a free genetic counseling appointment to go over results
  • CLIA-Certified & CAP-accredited lab
  • HIPAA-compliant to protect your data

Testimonials

What patients say about us

After I received my results from Probably Genetic, my doctor suddenly began running all sorts of tests/asking all kinds of questions, things I had told him but he never heard. So THANK YOU. I can't thank your company, your testing enough. It led to breakthroughs and actions from my doctors that would have never happened without you.

We've been searching for answers for over a decade and I'd almost given up. I'm so grateful that Probably Genetic has taken it upon themselves to make this kind of potentially life-altering testing accessible to families like mine.
