Ali AlBahar: DNA Drives the Molecular Era of Blood Typing
Ali AlBahar, Transfusion Medicine Specialist, Hematology and Blood Transfusion Researcher (MSc) at Ministry of Health Saudi Arabia, shared a post on LinkedIn:
“Blood group systems didn’t appear overnight.
They evolved.
Step by step.
Discovery after discovery.
Today (ISBT Classification):
- More than 45 Blood Group Systems
- More than Red Cell Antigens
We are now in the Molecular Era
Where blood typing is driven by DNA-based methods – not just serology.
Why this matters:
- Safer transfusion
- Less alloimmunization
- Precision matching
Key Shift
From serology to molecular science.
This journey reflects how transfusion medicine moved from basic serology to advanced molecular science
