The Platelet Supply Problem

Limited platelet supply and increasing demand are putting patients and hospitals at risk1,2

On average, 7,000 platelet transfusions are administered each day in the US.3 Oftentimes, hospitals struggle to meet this demand for platelets. Meanwhile, our rapidly aging population and enhanced transfusion safety requirements put a further strain on the available platelet supply.1,4

Without a safe, reliable source of platelets, some hospitals must postpone transfusions and surgeries, putting their patients at risk.2

STS is committed to helping meet the nation’s platelet needs with an innovative approach that taps an expanded, younger pool of prescreened donors to ensure a safe, consistent supply of platelets

The demand for platelets is projected to rise with a rapidly aging population1,5

Patients 50 years and older receive 81% of platelet transfusions in the US1

100% 81% 0%

The demand for platelets will only continue to grow1

By 2030, the population 65 years and older will increase by almost 18 million people5,6


The growing demand for platelets is outpacing the available supply.1

From 2017 to 2019 demand continued to grow7

Apheresis platelet transfusions increased 8% Total platelet transfusions increased by 15.8%

Demand is challenging supply as the donor base ages8

Federal mandates may constrain platelet availability even more4

The safety of platelet transfusions is critical, and the recent US Food and Drug Administration (FDA) mandate requires bacterial risk mitigation strategies such as large volume delayed sampling or pathogen reduction. Processing requirements associated with these bacterial risk mitigation strategies may further erode the platelet supply.

It takes approximately 3 hours to collect platelets, a time commitment that further limits the donor pool9
