Tareq Abadl: A Positive Antibody Screen is Not The Diagnosis
Tareq Abadl, Medical Lab Specialist, shared a post on LinkedIn:
”A Positive Antibody Screen Is Not The Diagnosis….
In Blood Bank, a positive screen is only the starting point.
When a patient has a history of previous transfusion, the laboratory must carefully evaluate the reaction pattern and correlate it with:
- Antibody screen
- Autocontrol and DAT
- Antibody identification panel
- Previous transfusion and pregnancy history.
The key question is not simply ‘What reacted?’
It is:
‘Why did it react?’
ASCP / BOC Pearl:
Always distinguish between alloantibody, autoantibody, and possible interference before moving toward transfusion management.
Blood Bank requires interpretation – not memorization.”
