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
