PDSA logo iconThe Platelet Disorder Support Association (PDSA) is dedicated to enhancing the lives of people with immune thrombocytopenia (ITP) and other platelet disorders through education, advocacy, research, and support. Patient-founded in 1998, PDSA connects ITP patients and caregivers with life-altering programs and support. We serve as a powerful force educating and unifying the global ITP community of patients, caregivers, practitioners, and key disease stakeholders and proudly serve as a trusted resource for the scientific community. Our comprehensive offering of programs and services not only empowers patients to better understand and take control of their disease, but also enables clinicians to stay current on the latest ITP protocols, cutting-edge research and innovative therapies being developed worldwide, so they can remain focused on exceptional patient care.

PDSA is committed to building awareness, educating the global community, and providing critical connections and resources that empower patients to take charge of their disorder and encourage practitioners to exercise patient-centered medical care. PDSA collaborates with other patient advocacy groups, researchers, and government agencies to drive public policy, develop new treatment options, and support research to find a cure.

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 website, personal counseling, local support groups, national and regional meetings, informative social media resources (PDSA.org, Facebook, Twitter, YouTube, Instagram, LinkedIn) or through our many publications.

Our goal is to offer patients diagnosed 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.
