tune Bank (Immunohematology) and Transfusion Services
Deals with the study of immunologic principles apply in kindred group antigens and antibodies
Also deals with mechanisms of line typing and bollocks matching, Coombs test, spying and measurement of antibody titers, screening of donors, release techniques, proper labeling, storage and disposal of transmission line with emphasis on quality assurance
Ensure that the donated blood or blood products be safe for blood transfusions
Blood banking tests include:
1. Blood typing
2. ABO and Rh typing
3. Compatibility testing or cross matching
4. Coombs test or Antihuman globulin test
5. Antibody screening test for detection and identification of unexpected antibodies
6. Donor screening is choosing the right font of blood from people
7.



Blood components preparation which is very classical in blood banking

BLOOD TYPING, ABO, AND RH TYPING
Blood products are blood components
Antigen is shew in the red blood cell
Antibody is found in the serum/ plasma
Some antigens related in Rh typing are:
* C antigen
* E antigen
* ? antigen
* ? antigen
* D antigen (most important)
Antigen| Rh+| Rh-|
D| +| -|
C| +| +|
E| -| +|
?| -| +|
?| -| +|

Blood type:
* 45%- O
* 40%- A
* 11%- B
* 4%- AB
MajorBlood groups| Antigen| Antibody| Can receive blood from:| Can give blood to:|
A| A| Anti- B| A, O (PRBC)| A, AB|
B| B| Anti- A| B, O (PRBC)| B, AB|
AB| A & antiophthalmic factor; B| none| AB, A, B, O (PRBC)| AB|
O| none| Anti- A & B| O| A, B, AB, O|
*PRBC= packed red blood cell

Reagents are expensive but procedures are wakeful to prepare
Anti-A and anti-B are considered expected antibodies (ABO typing)
Blood Group System
* ABO (cold antibody procedures)
* Rh (warm antibody procedures)
* Kidd
* Duffy
* Lewis
* P
* I
* MNSs
* Xg
* Lutheran
* Kell
Antibody procedures
* PILM- P...If you want to get a full essay, order it on our website: Orderessay
