History of Sport Purple for Platelets Day

Sport Purple for Platelets Day was established by the Platelet Disorder Support Association (PDSA) to bring attention to immune thrombocytopenia and other platelet disorders. The first observance took place on the last Friday of September, chosen because September is ITP Awareness Month. The color purple was selected to represent the condition, and the day encourages people to wear purple clothing and accessories to show solidarity with patients.

Over the years, the day has grown from a small awareness campaign into a global movement. Hospitals, schools, and community organizations now participate by hosting events, fundraising, and sharing information about platelet disorders. The PDSA continues to lead the effort, providing resources for individuals and groups to get involved.

Why is Sport Purple for Platelets Day important?

This day shines a spotlight on a condition that often goes unrecognized. Immune thrombocytopenia affects about 50,000 adults in the United States alone, yet many people have never heard of it. By wearing purple, participants start conversations that can lead to earlier diagnosis and better support for patients.

Raising funds is a critical component of the day. Research into new treatments and potential cures depends on donations. The day also provides a sense of community for patients and their families, reminding them they are not alone in their journey.
