59 Today's Veterinary Business • Equipment Guide 2017 In-house hematology tests provide complete blood counts and other data for disease detection and treatment monitoring. Newer models typically provide advance- ments in CBC and other blood values that can provide missing clues for certain patients. These clues can allow doctors to provide better answers to clients during the office visit. Running these tests in-house allows practices to start treatment in minutes if needed. Equipment overview A complete blood count (CBC) and differential/platelet count provide practitioners with a broad overview of a patient's general health and may help detect early disease, when treatment can be most effective. The CBC can also be helpful for monitoring treatment response to disease, making a prognosis and even preventing blood diseases. Many practices traditionally sent out CBC panels to an outside lab, having to wait 24 hours or more for results. In addition, during the time it takes a blood sample to reach the outside lab, the sample could become compromised by coagulation or cell deterioration. With a point-of-care hematology analyzer, the wait is reduced to 8 to 10 minutes (a little longer for additional panels). Plus the sample is fresh and has not broken down at this point. A hematology analyzer performing just a CBC usually reports values on white cells, red cells, hemoglobin, hematocrit, and distribution of certain factors within the blood cells. A hematology analyzer that also includes a differential/platelet count can report on neutrophil granulocytes, including band lymphocytes, monocytes, eosinophil granulocytes, and basophil granulocytes. Three basic types of in-house hematology analyzer technologies are used: • Laser flow cytometry with optical fluorescence and laminar flow impendence: These technologies scatter individual cells, recording size, nuclear characteristics, and cytoplasmic contents. This provides an advanced five-part white blood cell differential, absolute reticulocyte count, and banded neutrophil and nucleated red blood cell (nRBC) parameters. • Impedance counting: Cells are classified on size, based on the change in resistance as the particles pass through a small aperture between two electrodes. However, cell size is considered only limited data. • Quantitative buffy coat (QBC) analysis: Blood samples are separated (under high-speed centrifugation) into plasma, the buffy coat (containing white blood cells and platelets), and red blood cells. No five-part differential, banded neutrophils. The most advanced systems facilitate the veterinar y team's confident interpretation of a CBC, as well as differential cell counts and cell morphology. An accurate five -par t differential provides expanded information, gives veterinarians more clues into their patients' conditions, including serious bacterial, viral and parasitic infections. The more information veterinarians can glean from a CBC, the earlier and better they can diagnose and treat their patients, improving prognosis and the quality of life. Hematology analyzers
