A platelet donor is an individual who voluntarily donates platelets, a component of blood that helps with clotting. Platelets are crucial for patients undergoing treatments for conditions like cancer, trauma, or surgeries. The donation process typically takes about two hours and involves a machine that separates platelets from the rest of the blood, returning the remaining components back to the donor. Platelet donations can be made at blood donation centers or during blood drives. Donors are usually required to meet specific health criteria and may need to undergo a screening process. Regular platelet donors can significantly impact the lives of patients in need, contributing to their recovery and well-being.
