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 (IDF), founded in 1980, is the national non-profit patient organization dedicated to improving the diagnosis, treatment and quality of life of persons with PI through advocacy, education, and research. There are approximately 250,000 people who are diagnosed with PI in the U.S., and thousands more go undetected.
