What Does FNH Stand For?

FNH stands for Febrile Non Hemolytic Reaction

FNH, or Febrile Non Hemolytic Reaction, is a common adverse reaction that can occur during blood transfusions. Characterized by fever and chills, FNH typically arises from an immune response to white blood cells or plasma proteins in the transfused blood. Unlike hemolytic reactions, FNH does not involve the destruction of red blood cells. Although generally mild and self-limiting, it is important for healthcare providers to monitor patients for symptoms and manage them appropriately to ensure patient safety and comfort.
