What term refers to the abnormal clumping of red blood cells?

  1. Coagulation

  2. Hemolysis

  3. Agglutination

  4. Leukopenia

The correct answer is: Agglutination

The term that refers to the abnormal clumping of red blood cells is agglutination. This phenomenon occurs when red blood cells clump together, often in response to the presence of antibodies that bind to the antigens on the surface of the red blood cells. Agglutination can be a significant indicator of various conditions, such as blood type incompatibility during transfusions or autoimmune disorders where the body mistakenly targets its own red blood cells. In the context of veterinary medicine, recognizing agglutination is crucial for safely performing blood transfusions and diagnosing diseases that may affect the red blood cells. The microscopic examination of agglutinated red blood cells, either in a blood smear or through specialized tests, is an important part of evaluating a blood sample. Other terms that might seem relevant can often be confused with agglutination: - Coagulation refers to the process of blood clotting, which is distinct from the clumping of red blood cells. - Hemolysis is the breakdown or destruction of red blood cells, which is a different process than agglutination. It results in the release of hemoglobin into the bloodstream and can occur after agglutination if the cells are subsequently destroyed. - Leukopenia is the reduction
