Final answer:
In feline complete blood counts, the counted reticulocytes are Aggregate reticulocytes, which are indicators of the bone marrow's response to increased RBC demand.
Step-by-step explanation:
When evaluating feline reticulocytes on a complete blood cell count, the kind of reticulocytes that are counted is A) Aggregate reticulocytes. Reticulocytes are immature erythrocytes that may still contain fragments of organelles. They are normally released into the bloodstream from the bone marrow and, over a period of about a day, mature into erythrocytes, which circulate for an average of 120 days. In cats specifically, it's important to count the aggregate reticulocytes, which contain large clumps of RNA and organelle remnants and are indicative of active erythropoiesis, meaning that the bone marrow is responding to a demand for more red blood cells.
An elevated level of hemoglobin, whether adaptive or pathological, is termed polycythemia, and this may show up as an increased count in a hematocrit test. Diseases like polycythemia vera cause an excessive production of red blood cells (RBCs), while a decrease in RBCs could lead to various forms of anemia, with effects such as fatigue, lethargy, and increased susceptibility to infections.
