Blood Donations and Blood Banking

Table of content

A blood bank is a place where blood is collected as a blood donation and stored for later use in blood. The term “blood bank” usually refers to the hospital separation that occurs when a blood product is stored and undergoes a proper examination (to control the risk of adverse events added to the blood). However, sometimes it refers to a collection point, and some hospitals also do the collection. The blood bank includes functions related to blood collection, processing, testing, classification, and storage.

Blood Donations and Blood Banking

What is blood banking?

Blood transfusion is a procedure performed in a laboratory to ensure that blood is donated or that blood product is safe to use in transfusions and other medical procedures. Banking involves the signing of a blood test and the testing of infectious diseases.

Facts about blood banking:

  • Nearly 38,000 red cells are needed daily (2006).
  • The number of donated blood units is 16 million per year (2006).
  • There are approximately 9.5 million blood donors (2006).
  • Five million patients receive additional blood transfusions each year (2006).
  • Each piece of blood is broken down into fractions, such as red blood cells, plasma, and platelets. One portion of whole blood, if separated, can be added to several patients, each with different needs.
  • Each year, more than 30 million units of blood are- transfused

Who are the blood donors?

Many blood donors volunteer. However, in some cases, the patient may need to donate blood a few weeks before surgery- to obtain a blood transfusion so that blood transfusion may be needed. Giving your blood is considered a personal gift.

To further, ensure the safety of the blood supply system and the availability of blood, volunteer blood donors must pass alternatives, including the following:

  • Must be 16 to 17 years old
  • must be in good health
  • should weigh up to 110 pounds
  • must pass physical and medical examinations provided before submission

Some countries allow people under the age of 16 or 17 to donate blood with parental consent.

What tests are performed in blood banking?

A set of standard tests performed in a laboratory when a blood transfusion is- given, including, but not limited to, the following:

Type: ABO group (blood type)

Rh typing (good-and-bad antigen)

Randomized examination of immune cells that could cause problems in the recipient

Current or past viral tests including the following:

Hepatitis viruses B and C

Human immunodeficiency virus (HIV)

T-lymphotropic virus infection (HTLV) I and II

Syphilis

West Nile virus

• Irradiation to blood cells is- performed to degrade any T-lymphocytes present in donated blood. (T-lymphocyte can cause blood transfusions, but it can also cause so-called "graft-versus-host" problems with recurrence in other cells.

• "Reduced blood leukocyte" filtered to remove white blood cells that contain antibodies that can cause fever in recipients. (These antibodies, as well as additional antibodies, can also increase the recipient's risk of listening for an additional supplement.)

What are the blood types?

According to the American Association of Blood Banks, the distribution of blood types in the US includes the following:

• O Rh-positive - 39 percent

• Rh-positive - 31 percent

• B Rh-positive - 9 percent

• O Rh-free - 9 percent

• Rh-free - 6 percent

• AB Rh-positive - 3 percent

• B Rh-free - 2 percent

• AB Rh-free - 1 percent

What are the components of blood?

Although blood or some of its components are- transferred, each component performs many functions:

• Red blood cells - carry oxygen to the intestines and are often used to treat anemia.

• Platelets - helps blood clot and is used in the treatment of leukemia and other cancers.

• White blood cells - they help fight infections, and they help prevent them.

• Plasma - a fluid, a fluid component in the blood in which red blood cells, white blood cells, and platelets are- suspended. Plasma is needed to carry large amounts of blood through the bloodstream. Plasma performs many functions, including the following:

Helps maintain BP

Provides blood clotting proteins

It measured levels of sodium and potassium

Cryoprecipitate AHF: - a component of plasma that contains clotting factors- that help control bleeding.

Albumin, immune globulins, and clotting factor concentrate can also be- broken down by- fixed blood transfusions.
