Evaluating cellular components within a cat’s blood provides crucial insights into a range of health conditions, from infections and anemias to immune-mediated diseases and clotting disorders. This analysis offers valuable diagnostic and prognostic information, guiding treatment strategies and monitoring patient response.
-
Red Blood Cell Indices
Red blood cell (RBC) indices, including red blood cell count, hemoglobin concentration, and hematocrit, evaluate oxygen-carrying capacity. A low red blood cell count (anemia) can manifest as lethargy, pale gums, and weakness. Different types of anemia, such as regenerative anemia (where the bone marrow responds appropriately) and non-regenerative anemia (where the bone marrow response is inadequate), have varying underlying causes and prognoses, identifiable through RBC indices and morphology.
-
White Blood Cell Count and Differential
The white blood cell (WBC) count measures the overall number of white blood cells, reflecting the body’s immune response. A high WBC count can suggest infection or inflammation, while a low count may indicate certain viral infections or bone marrow suppression. The WBC differential further categorizes white blood cells (neutrophils, lymphocytes, monocytes, eosinophils, and basophils), providing more specific information about the nature of the immune response. For instance, elevated neutrophils often signal bacterial infections, while increased lymphocytes might suggest viral infections or certain types of leukemia.
-
Platelet Count
Platelets are essential for blood clotting. A low platelet count (thrombocytopenia) can lead to bruising and bleeding, while an elevated count (thrombocytosis) can increase the risk of blood clots. These abnormalities can be associated with various underlying conditions, including immune-mediated diseases, infections, and certain cancers.
-
Blood Smear Evaluation
Microscopic examination of a stained blood smear provides a visual assessment of blood cell morphology. This can reveal abnormalities in cell size, shape, and internal structures, aiding in the diagnosis of specific blood disorders.
