PDSA logo iconThe Platelet Disorder Support Association, founded in August 1998, is the nation’s foremost non-profit corporation to provide information and support and to encourage research about ITP and other platelet disorders. Our organization is devoted to offering the most timely, accurate, and comprehensive information about ITP and platelet disorders.

For many ITP patients and their families this disease is a roller coaster ride of emotions including feelings of helplessness, anxiety, fear, and depression. ITP can have a huge impact on the day-to-day physical and psychological aspects of a person’s life.

When someone is first diagnosed with ITP, PDSA is often the only place they can turn to for information and advice, aside from their doctor. PDSA is here for patients and their loved ones 24/7, whether it is through our personal counseling, our local support groups, our national and regional meetings, our informative online resources (PDSA.org, Facebook, Twitter, YouTube, Instagram) or through our many publications.

Our goal is to offer patients suffering with ITP and other platelet disorders answers to their questions with the most comprehensive and up-to-date information available, a personal connection to others, and a reassuring voice.

In the years since PDSA was founded, we have served as a beacon of hope for tens of thousands of individuals and families through education, advocacy, research and support. PDSA has become the primary resource for many ITP patients, families, and health care providers.

For a comprehensive list of the programs and services that PDSA provides, see our publication PDSA Makes the Connection to ITP.
