Veterinary Technician Practice Exam

A complete blood cell count measures which of the following?

1. Only red blood cells

2. Only white blood cells

3. Only platelets

4. All of the responses

The correct answer is: All of the responses

A complete blood cell count (CBC) is a comprehensive test that evaluates the different components of blood, which includes red blood cells, white blood cells, and platelets. This test provides valuable information about the hematologic status of the patient, helping veterinary technicians and veterinarians diagnose and monitor various health conditions. The assessment of red blood cells reveals important parameters like hemoglobin concentration, hematocrit levels, and red cell indices, which help in identifying anemia or polycythemia. The white blood cell count is crucial for evaluating the immune response and detecting infections or inflammatory diseases. Additionally, measuring platelets is essential for assessing the blood's clotting ability, which is vital in cases of bleeding disorders or during surgical procedures. The breadth of the CBC test, therefore, makes it a fundamental diagnostic tool in veterinary medicine, allowing for a holistic view of a patient's overall health. Each of the components measured provides critical insights that can guide treatment decisions and management plans.
