Study Notes
Blood Banking
- Blood banking refers to the collection, processing, preservation, preparation, and distribution of blood, blood components, and derivatives.
Scope and Function of a Modern Blood Bank
- A modern blood bank is responsible for:
- Recruiting blood donors
- Collecting and storing whole blood or components from volunteer or autologous donors
- Typing, screening, and preparing patients and donors for blood transfusion
- Detecting and identifying antibodies in potential blood recipients or pregnant women
- Establishing a database to support suspected or potential disorders
- Processing and dispersing blood components
- Performing paternity testing
- Conducting tissue typing prior to organ transplantation
Antibody Screening
- Antibody screening is used to detect antibodies in potential blood recipients or pregnant women
- Antiglobulin test (AGT) is used to aid in weak agglutination reactions
- There are two types of AGT: Direct (DAT) and Indirect (IAT)
- Coombs test is used to detect incomplete antibodies bound to a red cell membrane
Objectives of a Blood Bank Technologist
- Prevention of antigen-antibody production in the body
- To prevent antibody production, identifying patients who have been exposed to an antigen and may induce an antibody response
- Compatibility testing to ensure safe blood transfusion
- Determination of unexpected antibodies
History of Blood Transfusion
- 1492: Pope Innocent VIII attempted to use blood for therapeutic use
- 1665: Richard Lower performed the first animal-to-animal transfusion
- 1667: Jean Baptiste Denys performed the first successful IV transfusion of blood from animal to human
- 1818: James Blundell first transfused human to human
This quiz covers the process of determining blood type and the procedures involved in blood banking. It includes questions on blood grouping and the identification of antigens present or absent.
