We use an at-home saliva collection kit shipped to your door. You provide a saliva sample at your convenience, then mail it back using a pre-paid FedEx return label. No needles, no lab visits, no clinic appointments.

The sample is then analyzed by our HIPAA-compliant and CLIA certified partner laboratory (Prevention Genetics) to measure the CAG repeat count in your HD gene.

The saliva sample is no different from providing a blood sample.
