## What is Allergy 123?

The Allergy 123 app is the best way for health professionals to determine what allergens are really making their patients sick. Using state-of-the-art, patented algorithms practitioners can enter in allergy test results and have a suggested treatment set for their patient. Integrated into the Allergy 123 model of Test, Diagnose and Treat, this app will help practitioners treat the cause, not the symptoms of allergies.
