🩸 BLOOD GROUP IDENTIFICATION — ABO & Rh(D) TYPING

Ever wondered how your blood group is determined? 🔬
In forward blood typing, red blood cells are tested with Anti-A, Anti-B, and Anti-D (Rh) reagents.

🔴 Agglutination (clumping) = the corresponding antigen is present.
🩸 No agglutination = the corresponding antigen is absent.

For example:
• A+ → Anti-A (+), Anti-B (−), Anti-D (+)
• AB− → Anti-A (+), Anti-B (+), Anti-D (−)
• O+ → Anti-A (−), Anti-B (−), Anti-D (+)
• O− → Anti-A (−), Anti-B (−), Anti-D (−)

This simple reaction pattern allows laboratories to identify all 8 major ABO/Rh blood groups.

Save this as a quick reference 🧪🩸
