What is Pre-Transfusion Testing? |
A series of testing process include ABO and Rh typing of recipient's red cells to give best result of a blood transfusion. |
|
Why Pre-Transfusion Testing is needed? |
- To select blood component with acceptable survival. - To detect clinically significant unexpected antibodies. |
|
What is clinically significant antibodies? |
- Reactive at 37 degree celsius - Reactive in the Antihuman Globulin (AHG) Test - Caused transfusion reaction |
|
Why it is necessary to do antibody screening in Pre-Transfusion Testing? |
To test the patient's serum before transfusion to ensure patients has no significant antibodies to react with donor cells. |
|
What is the phase of test should be written in the result section of an antigram if the test is done using gel card? |
Only AHG Phase. |
|
In antibody identification, why we need to do Coombs Control Cells (CCC) for negative result in AHG phase? |
- To make sure whether the AHG has been added. - To make sure the AHG used is working. |
|
What is the last two steps of Pre-Transfusion Testing? |
- Selection of appropriate blood product - Cross matching |
|
For red blood cell (RBC) transfusion, what is the second choice if the recipient is blood group AB? |
Component with blood group A |
|
What are the types of cross matching?
|
- Immediate spin
- Computer crossmatch - Serologic (antiglobulin) crossmatch |
|
When should the Group Screen and Hold (GSH) compatibility test be used? |
- When involve only minor surgery - When antibody screening is negative |
