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
