Type AB blood, Rh negative

This code identifies a patient's specific blood type as AB negative. This means the red blood cells possess both A and B antigens but lack the Rh(D) antigen. This blood type is relatively rare and has significant implications for blood transfusions and pregnancy.

This code is used when documenting a patient's confirmed blood type, particularly in scenarios requiring blood product compatibility or risk assessment during pregnancy. It is crucial for pre-transfusion testing, prenatal care, and any situation where blood group incompatibility could be a concern.

• Always ensure the blood type has been definitively determined through laboratory testing.
• This code is for the type of blood, not for a reaction or complication related to it.
• Do not use this code if the Rh factor is unknown or positive.
