A veterinary hematology analyzer is a blood testing instrument used to count and analyze cells in whole-blood samples. Complete blood count (CBC) parameters help veterinarians assess hematologic status, monitor disease progression, and evaluate response to treatment. Cell differentiation capabilities, available parameters, and supported animal species vary by analyzer.<\/span><\/p>\n

When selecting an analyzer, facilities should consider the animal species to be tested, clinical needs, sample volume, analytical performance, and operating costs. The number of reported parameters or the stated testing speed is only meaningful if the analyzer meets the facility\u2019s actual needs.<\/span><\/p>\n

Before Choosing a Veterinary Hematology Analyzer, Answer These 4 Questions<\/b><\/h2>\n
    \n
  1. Which animal species does the facility test?<\/b>
    \n<\/b>Do not only check which species are pre-programmed into the analyzer. Review the performance of each parameter for those species as well.<\/span><\/li>\n
  2. What level of white blood cell differentiation is needed?<\/b>
    \n<\/b>The main difference between 3-part and 5-part analyzers is their ability to differentiate white blood cells. More categories do not automatically mean the analyzer is more suitable.<\/span><\/li>\n
  3. What is the actual sample volume?<\/b>
    \n<\/b>The stated testing speed is only useful when it matches the number of samples processed each day, peak-hour demand, and the facility\u2019s quality-control procedures.<\/span><\/li>\n
  4. What are the costs after purchasing the analyzer?<\/b>
    \n<\/b>Operating costs should include reagents, quality-control materials, maintenance, consumables, staff training, and downtime when the analyzer requires servicing.<\/span><\/li>\n<\/ol>\n

    What is a veterinary blood analyzer?<\/b><\/p>\n

    Hematology analyzers and CBC testing<\/b><\/h3>\n

    \u201cVeterinary blood analyzer\u201d is a broad term that may include hematology analyzers, biochemistry analyzers, and other analytical systems. A hematology analyzer specifically evaluates blood cells and reports CBC parameters.<\/span><\/p>\n

    Depending on the design, an analyzer may use electrical impedance, optical methods, or a combination of methods to count and differentiate cells. Parameters may be measured directly or calculated from measured values according to the analyzer\u2019s configuration.<\/span><\/p>\n

    CBC testing is commonly used to support the assessment of anemia, changes in white blood cells, and abnormalities in platelet counts. In some cases, a blood smear examination is also needed to assess cell morphology, identify cell clumping, or verify analyzer results.<\/span><\/p>\n

    How is a hematology analyzer different from biochemistry, immunoassay, and PCR systems?<\/b><\/h3>\n\n\n\n\n\n\n\n
    Instrument or system<\/b><\/td>\nWhat it analyzes<\/b><\/td>\nInformation provided<\/b><\/td>\n<\/tr>\n
    Hematology analyzer<\/span><\/td>\nCells in whole-blood samples<\/span><\/td>\nCell counts and other cellular characteristics the analyzer is designed to assess<\/span><\/td>\n<\/tr>\n
    Biochemistry analyzer<\/span><\/td>\nSubstances and enzyme activities in appropriate sample types<\/span><\/td>\nParameters that support assessment of liver and kidney function, metabolism, and electrolyte balance, depending on the test menu<\/span><\/td>\n<\/tr>\n
    Immunoassay system<\/span><\/td>\nAntigens, antibodies, hormones, or biomarkers<\/span><\/td>\nResults depend on the method, test kit, and sample type<\/span><\/td>\n<\/tr>\n
    PCR or RT-PCR system<\/span><\/td>\nNucleic acids of the target being tested<\/span><\/td>\nDetection of target DNA or RNA according to the relevant testing procedure<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    These test groups provide different types of information. A CBC does not replace biochemistry testing for assessing metabolic problems or specialized testing for identifying disease-causing agents. Veterinarians select tests according to the animal\u2019s condition and the diagnostic objective.<\/span><\/p>\n

    Which Parameters Are Included in a Veterinary CBC?<\/b><\/h2>\n
    \"Laboratory
    A veterinary CBC includes red blood cell, white blood cell, and platelet parameters such as RBC, HGB, HCT, WBC, and PLT, which support assessment of an animal\u2019s hematologic status.<\/figcaption><\/figure>\n

    Red blood cell parameters: RBC, HGB, HCT, MCV, MCH, and MCHC<\/b><\/h3>\n

    Red blood cell parameters support the assessment of anemia, erythrocytosis, and characteristics of the red blood cell population. Common parameters include:<\/span><\/p>\n\n\n\n\n\n\n\n\n\n
    Parameter<\/b><\/td>\nBasic meaning<\/b><\/td>\n<\/tr>\n
    RBC<\/span><\/td>\nNumber of red blood cells per unit volume of blood<\/span><\/td>\n<\/tr>\n
    HGB<\/span><\/td>\nHemoglobin concentration in the blood<\/span><\/td>\n<\/tr>\n
    HCT<\/span><\/td>\nPercentage of total blood volume occupied by red blood cells<\/span><\/td>\n<\/tr>\n
    MCV<\/span><\/td>\nAverage volume of a red blood cell<\/span><\/td>\n<\/tr>\n
    MCH<\/span><\/td>\nAverage amount of hemoglobin in a red blood cell<\/span><\/td>\n<\/tr>\n
    MCHC<\/span><\/td>\nAverage hemoglobin concentration within the red blood cell mass<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    RBC, HGB, and HCT should be interpreted together and considered alongside the animal\u2019s clinical condition and sample quality. MCV and MCHC can help classify anemia, but they are not sufficient to determine the cause based on a single result.<\/span><\/p>\n

    Reference intervals should be appropriate for the animal species, testing method, and population being assessed. Age, physiological status, and other factors can also affect interpretation.<\/span><\/p>\n

    White blood cell parameters: WBC and differential counts<\/b><\/h3>\n

    WBC is the total number of white blood cells per unit volume of blood. White blood cell counts can change in many situations, including inflammation, infection, stress, medication effects, or bone marrow disorders. WBC alone does not identify the cause.<\/span><\/p>\n

    In addition to total WBC, some analyzers classify white blood cells into different groups:<\/span><\/p>\n
