Description

The ABO Group test determines your blood type—A, B, AB, or O—and whether you are Rh-positive or Rh-negative.

Your blood type is based on the presence or absence of two antigens (A and B) on the surface of red blood cells. The Rh factor is another antigen (a protein) that can be either present (Rh-positive) or absent (Rh-negative). Together, these markers determine what type of blood you can safely receive or donate.

Why This Test Is Important

1. Safe Blood Transfusions

  • Receiving incompatible blood can cause a serious and potentially life-threatening reaction.
  • Knowing your type ensures the safest match if you ever need a transfusion.

2. Organ & Tissue Transplants

  • Blood type compatibility is essential for successful organ or bone marrow transplants.

3. Pregnancy Care

  • Pregnant women with Rh-negative blood may need special monitoring and treatment if their baby is Rh-positive, to prevent Rh incompatibility and protect the baby’s health.

4. Emergency Preparedness

  • Having your blood type on record speeds up emergency care if you ever need urgent transfusion or surgery.
