What reaction is indicated by symptoms such as fever, chills, and signs of hemoglobinuria?

• A. Febrile
• B. Hemolytic
• C. Septic
• D. Anaphylactic

Answer: (B)

The symptoms of fever, chills, and hemoglobinuria point towards a hemolytic reaction. In this type of reaction, the immune system is triggered to attack red blood cells, often resulting from the transfusion of incompatible blood types. The breakdown of red blood cells releases hemoglobin into the bloodstream, which can then be filtered out by the kidneys, leading to hemoglobinuria. This condition is characterized by the appearance of hemoglobin in urine, often giving it a dark color. The presence of fever and chills also supports the diagnosis of a hemolytic reaction, as these systemic symptoms can arise from the release of pyrogens during the destruction of red blood cells. Recognizing these symptoms as indicative of a hemolytic reaction is crucial for timely medical intervention, which can minimize complications and safeguard patient health. In contrast, febrile reactions typically involve fever without hemoglobinuria, septic reactions may also present with fever but are associated with an infection, and anaphylactic reactions would present with different symptoms, primarily respiratory distress and allergic manifestations rather than specific signs of hemolysis.
