What happens to donated blood?
When one gives blood, it is just the beginning of a much longer process to get blood to a person in need. Donated blood must take a few steps. First, a part of the blood is tested and the rest of the gift is processed. Then the blood is stored before it is finally used to help people with the medical need for blood or blood components. In order to maintain blood safety, donated blood is thoroughly tested for various diseases and to confirm the type. This is done if the donors are wrong about their blood type or if they have been infected with a disease they do not yet know. Donated blood is tested on the rheses (RH) factor; for common types of blood A, B, AB and O; And for unusual antibodies and blood types. If any of the test results is positive to the disease, the donor is informed and the gift is not USED.
Some of the infectious diseases or agents causing diseases is donated blood tested on including the human virusHo immunodeficiency of type 1 and 2 type (HIV), a virus that causes immunodeficiency syndrome (AIDS) and hepatitis B and C. Other tested for virus, syphilis, syphilis and human virus. The tests are looking for antibodies that create a system of exposed persons. In some cases, they also look for nucleic acids created by the virus. These tests are essential because the person can be exposed to these agents, but does not show symptoms and this substance may be when they are received through blood transfusion.
During testing, the rest of the donated blood usually goes through processing where it is ready for use or can be stored as full blood. During processing, the donated blood is divided into Parts or components such as red cells, platelets and plasma, is a spin in a centrifuge. Plasma can also be processed further on a substance called Cryoprecipitate. The components also subject to a process called leukoreduction, which is the removal of white blood cells, so they do not interfere with the immune systemMU of the patient. Separate components can then be used to treat multiple patients with different conditions, so one pint of blood can help more than one patient.
further, donated blood goes to storage until it is needed. Storage methods and storage times vary depending on the blood component. The plates must be stored at room temperature and maintained in constant movement in the agitator and last only five days. The whole blood must be cooled and can be safely stored for 35 days and red blood cells can be cooled for 42 days. Plasma and cryopreciation have the longest storage time - up to one year - and are seeds.
Finally, when needed, donated blood is distributed to hospitals to be used in the treatment of different conditions. The whole blood is often needed for patients with surgery and trauma victims. Red blood cells are useful in the treatment of anemia of sickle cells and standard anemia, as well as any other significant blood loss. Plates are used for the treatment of a specifiedof all cancers such as leukemia; Plasma is used for disorders of clotting and burns; And cryopreciation is very useful in the treatment of haemophilia. Many blood banks are able to at any time, at any time, at any time to hospitals, at any time to hospitals, at any time.
