Changing the Lives of People With Primary Immunodeficiencies (PI) With Early Testing and Diagnosis

Throughout the world, primary immunodeficiencies (PI) are largely undiagnosed and underreported. Many patients do not receive an accurate and timely diagnosis, which is crucial for successful management and care of PI (1). It is estimated that between 70 and 90% of people living with a PI still remain undiagnosed worldwide (2). As for many other rare diseases, early testing and diagnosis are essential first steps in the care pathway toward timely and appropriate care and treatment, which are ultimately life changing and life enhancing for people living with PI. Under the theme "My future starts with early testing and diagnosis of PI," the eighth annual World Primary Immunodeficiency Week (World PI Week), celebrated from the 22nd to the 29th of April 2018, raised awareness of early recognition of PI, pursuing the goal of the campaign of ensuring an improved quality of life for people living with these diseases worldwide.
