About the Platelet Disorder Support Association

Our Mission:

The Platelet Disorder Support Association is dedicated to enhancing the lives of people with immune thrombocytopenia (ITP) and other platelet disorders through education, advocacy, research and support.


The Platelet Disorder Support Association is a non-profit corporation founded in August, 1998 to provide information, offer support, and encourage research about ITP and other platelet disorders.

It all began as a simple idea in the spring of 1997, construct a Web site that provided a place to share our ITP stories. Since its inception, pdsa.org has grown to over 200+ pages of FREE 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 for medical professionals and patients with ITP and other platelet disorders.

In the years since PDSA was founded, we have served as a beacon of hope for more than 25,000 individuals and families through information, referral, patient support, education, research and advocacy.

Our services promote patient-to-patient, patient-to-physician, and patient-to-medical provider communication. We encourage patient involvement in treatment and life-style decisions.

Public Education

Through contacts with the media and the publication of educational materials, we strive to increase the amount of information presented and available about ITP and other platelet disorders.

Platelet Disorder Research and Advocacy

We assist and encourage research in the treatment of ITP and other platelet disorders through surveys and collaboration with the National Institutes of Health, physicians, and researchers. We attend medical conferences and health care-related meetings and report any significant research and news that pertains to diagnosis and treatment of ITP to our members.
