Karl Landsteiner discovered ABO blood group system in the early 20 century, but still, uncertainty remains in immunohematology while detection of ABO subgroups or weaker variants.

We here report a case of the B(A) phenotype in a patient who was diagnosed with chronic liver disease with acute pancreatitis, requiring packed red blood cells due to anemia.
