Genetic Testing

Genetic testing is available for any suspected or clinically diagnosed HHT patient. For information, please contact your medical HHT specialist.

This test is valuable to families affected by HHT. A simple blood sample will help family members know if they are affected by the disease, even if they have yet to show symptoms.
