Study Notes
Blood Banking and Transfusions
- The main function of a blood bank is to collect, test, and distribute blood and blood components to patients in need.
Tasks in Blood Banking
- Blood banking involves several tasks, including:
- Blood collection and processing
- Blood testing (e.g., typing, screening for infectious diseases)
- Storage and distribution of blood and blood components
- Matching of donor and recipient blood types
- Preparation of blood products (e.g., red blood cells, plasma, platelets)
Blood Transfusions
- Patients with anemia or iron deficiency typically receive a packed red blood cell (PRBC) transfusion.
- The purpose of transfusing red blood cells or packed cells is to increase oxygen delivery to tissues and organs.
Antibody Elution Procedure
- The antibody elution procedure is used in clinical laboratory diagnostics to:
- Identify antibodies in a patient's blood that react with donor red blood cells
- Determine the specificity of antibodies in a patient's blood
- An antibody elution is deemed necessary when a patient has a history of multiple transfusions or has developed antibodies against donor red blood cells.
Routine Tests in Clinical Blood Banks
- Examples of routine tests used in clinical blood banks include:
- ABO and Rh blood typing
- Antibody screening
- Cross-matching
- Infectious disease testing (e.g., HIV, hepatitis)
Treatment with Thiol Reagent
- Treatment with thiol reagent is used in specialized tests to:
- Enhance antibody detection
- Improve the sensitivity of antibody testing
- In the context of clinical blood banks, antibody elutions aid in investigating:
- Hemolytic disease of the fetus and newborn
- Hemolytic transfusion reactions
- Autoimmune hemolytic anemia
