Blood Donation Clinics
Most hospitals have blood banks, where blood is stored under specific conditions. It will have preservatives or anticoagulants in it to help with the process of storage. Stored this way most blood has a thirty five day shelf life.
With the pressure on the economy, many people are resorting to selling their blood or plasma at blood banks or blood collection centers. These centers are also strictly regulated. No one will get rich this way, but may help pay a bill, and so the practice continues.
Blood donation clinics and blood plasma clinics are monitored and restricted. The best ones are recognized by the peers who evaluate their functioning. Most large cities have at least one blood donation center.
One other type of blood donation may be mentioned. It would be done in a hospital setting in preparation for having surgery. When you donate and bank your blood for your own use, it is called autologous donation and it is one way that many people prepare for a scheduled or elective surgery.
