Rhnegatívnak

Rhnegatívnak refers to an Rh-negative blood type. The Rh factor is an inherited trait that refers to the presence or absence of a specific antigen, the D antigen, on the surface of red blood cells. Individuals who lack this antigen are considered Rh-negative. This classification is crucial in medical contexts, particularly during blood transfusions and pregnancy.

In transfusions, an Rh-negative recipient should ideally receive Rh-negative blood. Transfusing Rh-positive blood to an Rh-negative person can lead to the development of antibodies against the Rh factor. If this occurs, subsequent transfusions of Rh-positive blood can cause a serious transfusion reaction.

During pregnancy, Rh incompatibility can arise if an Rh-negative mother carries an Rh-positive fetus. The mother's immune system may recognize the fetus's Rh-positive red blood cells as foreign and produce antibodies. This can lead to hemolytic disease of the newborn (HDN), a condition where the baby's red blood cells are destroyed, potentially causing anemia, jaundice, and even more severe complications. Fortunately, Rh immune globulin (RhoGAM) can be administered to Rh-negative mothers to prevent antibody formation and protect the fetus.
