Why must D-Positive blood not be transfused into a D-Negative patient?
Transfusing D-positive blood into a D-negative patient can lead to an immune reaction. The D antigen is part of the Rh blood group system, and a D-negative individual can produce antibodies against the D antigen if exposed to D-positive blood, potentially causing a severe transfusion reaction.
What type of blood can a person with type B RH-negative receive?
A person with Type B Rh negative blood can receive B Rh negative red cells or O Rh negative red cells. If no Rh negative blood is available, this person could receive B or O Rh positive blood, but this would not be recommended for women of child bearing age as the exposure to the D antigen (D is the Rh positive part) may cause this person to form an antibody against the D (Rh) antigen (Anti-D). Anti-D may cross the placenta and attach to D positive cells in the fetus leading red cell destruction and other serious consequences.
What does plus and - stand for in blood group?

What is DU negative factor in blood?
Rh blood type is determined by the presence or absence of the D antigen. People who are Rh positive have the D antigen and those that are Rh negative lack this. Some people have a variant of the D antigen, called Du. Presence of Du antigen causes lab results to report the blood type as Rh negative, although the patient behaves as an Rh positive would. Du negative means a "true Rh negative" result.
What does A Rh D POS mean as your blood group?

It's important in blood transfusions and pregnancy, as it can affect compatibility between blood types.
