The benefits of blood donation include stimulation of bone marrow hematopoiesis, maintenance of active bone marrow hematopoiesis, and free blood for life after a certain level of blood donation.
People who donate blood will lose more blood in a short period of time, which will stimulate bone marrow hematopoiesis, and repeated blood donations will maintain bone marrow hematopoiesis in an active state.
Currently, it is the policy of China that blood donors can use blood free of charge for life after they have accumulated more than 1,200 milliliters of blood.
Such a policy is formulated to encourage people to donate blood free of charge, because the clinical application of blood products is indispensable, and blood products cannot be synthesized artificially, but can only be prepared through people’s blood donations, so to ensure an adequate supply of blood can to a certain extent ensure the safety of patients using blood in the clinic.
