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.”
