3. Have you ever wondered if you are at risk for any of these conditions?

4. Finding out can bring peace of mind... “I was floored when I read my Navigenics results which found that my highest elevated risk condition (96-98%) was colon cancer - I have just been diagnosed with colon cancer. Had I known my genetic risk years ago, I may have been more proactive and caught it even earlier. The cost is a small price to pay to prolong your life, especially if you have young kids or a family to provide for. “ -Sempra finance employee, Female, 51

5. Finding out can bring peace of mind... “There’s a condition that I have 16 times the risk of developing as compared to the general population: macular degeneration. When added to the fact this is the reason that my grandmother is currently going blind, I’m suddenly a very motivated participant in my own health. While it’s a scary risk number, I’m now positioned to have an impact on it, and I’m incredibly happy that I know about it.” -Microsoft program manager, Male, 30

6. Finding out can bring peace of mind... “For years, I experienced stomach problems that never went away. My sister encouraged me to get a Navigenics genetic test and my results showed I was at high risk of celiac disease. My doctor recommended I cut out gluten from my diet, and in the three weeks since I changed my eating habits, I’ve lost eight pounds and my stomach problems have disappeared.” -Urgent care employee, Female, 23

7. Finding out can bring peace of mind... “My analysis was mostly reassuring, but showed two areas of increased risk. One was celiac disease, which was a surprise. I followed up the Navigenics report with a serologic test and an upper endoscopy, which were positive for moderately severe celiac disease. It is amazing to me, at the age of 52 years, and being a physician, that my diagnosis and treatment was possible only because of your DNA test.” -Head of oncology company, Male, 52
