About ABO Group and Rhesus (Rh) Factor
The ABO Group and Rhesus (Rh) Factor are critical blood group systems. The ABO blood group system is based on the presence of antigens and antibodies in the blood, specifically the A and B antigens. The Rhesus factor denotes the presence or absence of the D antigen on the surface of erythrocytes, which determines whether the blood type is Rh-positive or Rh-negative. These blood group systems are vital for blood transfusions, organ transplants, and pregnancy management.

Health Implications
High
Having an ABO blood group with less common antigens or an Rh-factor mismatch during pregnancy can lead to immune reactions, such as hemolytic disease of the newborn.
Low
While rare, a lack of certain ABO antigens can increase susceptibility to infections or cause complications in blood transfusions due to mismatched donor-recipient compatibility.
Symptoms
High
May include fatigue, jaundice, headaches, and high blood pressure, indicating potential hemolytic reactions or other underlying conditions.
Low
Can include dizziness, pale skin, weakness, and shortness of breath, suggesting anemia or low blood volume.
