Lewis Blood Group System is a human blood group unlike most others. The antigen is produced and
secreted by exocrine glands, eventually adsorbing to the surface of red blood cells. Its expression is

expression to be?
A. Le (a- b-)
B. Le (a+ b+)
C. Le (a+ b-)
D. Le (a- b+) - ANS - C

A. Type AB red blood cells can be transfused to this patient
B. Type O red blood cells can be transfused to this patient in an emergency
C. Type O NEG blood can be transfused to this patient
D. Patient can receive only Bombay phenotype blood - ANS - D
