A blood bank is a place for stocking blood donations from donors. The blood that is donated to a blood bank is used by other people who are in need of blood transfusions. The blood that will be transferred to another person must be compatible with the blood of that individual. Blood testing is first done to know what time of blood is carried by a person.
Here are the steps on how a blood bank network functions:
- Blood donations. People go to central blood banks to donate blood. Sometimes, the hospital goes to a blood collecting agency to get blood for blood transfusions. Delta Blood Bank is an organization that educates people regarding the need for donating blood. In some cases, the blood donor is paid for the blood that was given to the bank. Any blood type is accepted at blood banks. The blood that is used for transfusion typically comes from donors who are not paid. The plasma blood from paid donors goes through some processes before it can be used.
- Whole blood. Whole blood is the name given to blood that is not separated. This blood is mixed with a preservative in order for it to be used. This blood can last up to 35 days. In some cases, the blood goes through a process of separating its components. The red blood cells from the blood are mixed with a component that allows it to be usable for up to 42 days. The blood is then placed in a blood storage unit and frozen. When the blood is frozen, it can last up to ten years.
- Blood plasma. The blood plasma that was separated from the red blood cells is also frozen. There are several uses for this blood plasma. Some uses for the blood plasma are for transfusion or for fractioning.
- Platelets. Another element that is separated from the blood is the buffy coat. The buffy coat is the element that is used to make blood platelets. Blood platelets are also used in blood transfusion. Unlike the red blood cells, the buffy coat is stored at room temperature. It can last up to five days.
- Storage. In cases where the red blood cells are rare, cryopreservation is done. This is the process of freezing the blood at subzero temperatures. This allows the blood to be usable for up to 10 years. There is a solution called glycerol that is mixed with the red blood cells. The glycerol is mixed with the red blood cells to ensure that they will not be damaged due to the very low temperature.
- Cord blood bank. A cord blood bank is a facility that stores blood that is taken from the umbilical cord. This blood can still be used for other purposes, such as curing immune systems and different blood ailments.
This is how a blood bank functions. Blood banks are a great resource for hospitals and clinics. Other people will have a chance to help out ailing patients that need blood donations. Some people are helped by the blood bank, which pays them for the blood that they donate.
