Short Answer
Platelets are often in short supply because they expire quickly and patients need them every day.
Detailed Explanation
Unlike many blood components, platelets cannot be stored for long periods. Hospitals require a continuous supply for cancer patients, bone marrow transplant recipients, dengue patients with severe thrombocytopenia, and people undergoing major surgeries.
Since they expire within a few days, blood banks rely on regular platelet donors throughout the year.
Key Points
- Platelets expire within about 5 days.
- Demand exists every day.
- Cancer treatment requires regular platelet transfusions.
- Seasonal illnesses such as dengue can rapidly increase demand.
❤️ A regular platelet donor helps ensure that hospitals never run out when patients need them most.
