Peutz-Jeghers syndrome can be confirmed by genetic testing. A genetic test looks for changes in your DNA that cause areas of your body to not work properly. A small tube of blood or a saliva sample is collected and sent to a specialized laboratory for testing.
Genetic testing for Peutz-Jeghers syndrome has to be ordered by a medical professional, such as a doctor or a genetic counselor, after a visit to the medical clinic. Visit the National Society of Genetic Counselors website to learn more about genetic counseling services and to find a genetic counselor in your area.
