PATHOLOGY

Detailed explanation-1: -blood group B – has B antigens with anti-A antibodies in the plasma. blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma. blood group AB – has both A and B antigens, but no antibodies.

Detailed explanation-2: -B+ (B positive) if you have B and rhesus antigens. B− (B negative) if you have B antigens but don’t have rhesus antigens. AB+ (AB positive) if you have A, B and rhesus antigens. AB− (AB negative) if you have A and B antigens but don’t have rhesus antigens.

Detailed explanation-3: -Red blood cell antigens determine your blood group The antigens expressed on the red blood cell determine an individual’s blood group. The main two blood groups are called ABO (with blood types A, B, AB, and O) and Rh (with Rh D-positive or Rh D-negative blood types).

Detailed explanation-4: -It was not until the year 1900, when Karl Landsteiner at the University of Vienna, discovered why some blood transfusions were successful while others could be deadly. Landsteiner discovered the ABO blood group system by mixing the red cells and serum of each of his staff.
