Summary
A novel Kell blood group antigen, anti-K19, was identified in a patient lacking the antigen. This discovery expands understanding of Kell system diversity and rare blood types.
Area of Science:
- * Immunology
- * Transfusion Medicine
- * Genetics
Background:
- * The Kell blood group system is a complex and clinically significant red blood cell antigen system.
- * Rare Kell phenotypes and antibodies pose challenges in blood transfusion compatibility.
