Having a primary immunodeficiency (PI) affects your overall health. In addition to understanding your specific disease type, it is helpful to know how your immune system works, how PI is inherited and diagnosed, and how it can affect other aspects of your health.

The Immune Deficiency Foundation improves the diagnosis, treatment, and quality of life of people affected by primary immunodeficiency through fostering a community empowered by advocacy, education, and research.
