Blood Type Testing

Blood type testing determines a person's blood group based on specific markers on red blood cells. The main blood types are A, B, AB, and O, which can be either Rh-positive or Rh-negative, depending on the presence of the Rh factor. This classification is crucial for safe blood transfusions, organ transplants, and maternal-fetal compatibility. During the test, a small blood sample is mixed with antibodies; if agglutination occurs, it reveals specific blood characteristics. Knowing your blood type can be vital in emergencies and helps healthcare providers make informed decisions regarding treatments.
