Platelet donation means that platelets from blood donors are separated out through a blood cell separator, processed and stored, and then applied to patients with thrombocytopenia. The precautions for platelet donation are: i. People suffering from blood system diseases are not able to donate platelets, such as patients suffering from aplastic anemia, leukemia, myelodysplastic syndrome, lymphoma and other patients are not able to donate platelets. Second, if you have recently taken anti-platelet drugs, such as aspirin and Bolivar, you are not able to donate platelets. This is because platelet donation may induce a rebound increase in platelets, which may lead to thrombosis and embolic diseases. People who are positive for hepatitis B surface antigen, hepatitis C antibodies, HIV antibodies or syphilis antibodies should not donate platelets, as these antibodies may carry infectious blood viruses and lead to the transmission of these diseases.
