Description

A blood group test, also known as blood typing or ABO and Rh typing, determines a person's blood type (A, B, AB, or O) and whether they are Rh-positive or Rh-negative. This information is crucial for blood transfusions, organ transplants, and during pregnancy to prevent complications. The test involves mixing a blood sample with antibodies to detect the presence or absence of specific antigens on red blood cells.
