Rh Factor

The Rh factor is a protein found on the surface of red blood cells. People are classified as Rh-positive if they have this protein and Rh-negative if they don’t. This classification is important in blood transfusions, pregnancy, and organ transplants. If an Rh-negative person receives Rh-positive blood, their immune system may react negatively. In pregnancy, if an Rh-negative mother carries an Rh-positive baby, it can lead to complications unless managed with medical care. Understanding Rh factor helps ensure safe medical procedures and healthy pregnancies.
