    Organization Veterinary Hematology and Clinical Chemistry is organized into six sections, arranged as follows: I: presents principles of laboratory technology and test procedures used in veterinary laboratories to generate laboratory results.

    It also presents perspectives on how laboratory data interpretation is used in diagnosis and overall clinical case management. II: presents hematology and hemopathology of common domestic species. This includes all aspects of the hemogram or complete blood count, bone marrow, hemostasis, and transfusion medicine. III: presents hematology of common nondomestic species encountered in veterinary practice. IV: presents clinical chemistry of common domestic species and is organized primarily by organ system.

    V: presents clinical chemistry of common nondomestic species.

    VI: is a compilation of clinical cases. Each case includes a signalment, brief history, and pertinent physical examination findings. Then, relevant laboratory data are presented in tables followed by a narrative interpretation of the data.

    Revisions and additions Some of the more important revisions and additions include the following. The overview of laboratory technology has been updated to reflect continued advances in and adoption of in-clinic diagnostic instrumentation and capabilities.

    Some of the historical laboratory procedures that are no longer used have been removed. Next, we comment on data interpretation skills. Our experience indicates that veterinarians are reasonably adept at understanding how laboratory tests relate to pathophysiology, but then don t think probabilistically about the magnitude of data abnormalities and often struggle interpreting complex data sets.

    Rules for interpreting diagnostic tests assume homogeneity of pathophysiologic responses, or that our animal friends have read the book ; as imagined in Figure P.

    However, we know that there are many variables that create considerable biologic variability in expected responses. Chapter 3, Perspectives in Data Interpretation, has been revised to provide introductory guidance to build the skill set required for adroit interpretation of laboratory data.

    This involves development of flexible, probabilistic thinking skills when solving the complex puzzle formed by the array of clinical findings and laboratory data. Extensive revision and some additions have been made possible for selected chapters by incorporation of content from new authors.

    Examples include: x 13 Preface Figure P. Not all will read the book. Courtesy of Dr. Sara Hill. Wayne Jensen, Morris Animal Foundation, provides an update of the rapidly evolving area of immunodiagnostics. Advances have continued to be made in the diagnosis and classification of hematopoietic cell neoplasia. A new chapter from Anne Avery, Colorado State University, provides an overview of evolving molecular and flow cytometric diagnostics applied to hematopoietic neoplasia.

    This complements the other chapters detailing leukocyte responses, bone marrow evaluation, and hematopoietic proliferative disorders. Robin Allison, Oklahoma State University, has made extensive revision of laboratory diagnostics related to pathology involving liver, pancreas, blood proteins, and muscle.

    Andrea Bohn and Glade Weiser, Colorado State University, have revised the often-dreaded subjects of electrolyte and acid-base pathology, with an attempt to simplify clinical understanding of these laboratory tests. Last, but not least, Don Meuten, North Carolina State University, brings his extensive experience and expertise cultivated from too many years in both anatomical and clinical pathology.

    He contributes new treatment of renal, endocrine, and calcium metabolic pathologies. The Clinical Case Presentations were a separately bound supplement to the 1st Edition. In the 2nd Edition, the Clinical Case Presentations are incorporated into this singlebound textbook. These presentations are intended to provide students practice to develop interpretive skills by seeing examples of how data are interpreted into pathologic processes and how pathologic processes may culminate in a diagnostic scenario.

    The original cases are retained because their classical usefulness does not change. In addition, a number of new cases have been added by some of the new contributing authors. It is our wish that readers not only learn principles and skills from this work, but also enjoy interacting with it. As veterinarians and specialists in bioanalytical pathology, we share our passion for the art and science of laboratory diagnostics applied to animal health.

    The product of a collaborative effort by a team of experts in the field, this text combines critical information about performing diagnostic tests, viewing pertinent clinical pathology, and interpreting laboratory data with an innovative approach to incorporating color visual content. Audience A current trend in the field is the movement of laboratory diagnostics into the veterinary facility, enabled by technological advancements in point-of-care diagnostic capability.

    This movement to in-house testing increases the need for education in veterinary clinical pathology. Although this book was written primarily for veterinary students and practitioners, it has applications for a much broader audience, serving as a useful adjunct for the educational and reference needs of a variety of other users.

    The following audiences will benefit from this resource: Students in professional veterinary medical education programs Veterinary health professional teams in veterinary care facilities Veterinary clinical pathologists and clinical pathologists in training Research and product development groups utilizing veterinary clinical pathology Organization Veterinary Hematology and Clinical Chemistry is organized into six parts, arranged as follows: Part I presents principles of laboratory technology and test procedures used in veterinary labs to generate laboratory results.

    Part II presents hematology and hemopathology of common domestic species. Part III presents hematology of common nondomestic species encountered in veterinary practice. Part IV presents clinical chemistry of common domestic species and is organized primarily by organ system.

    Part V presents clinical chemistry of common nondomestic species.

    Comparative Clinical Pathology

    Unique art program Many aspects of veterinary clinical pathology are highly visual. The most unique feature of this book is the quantity and quality of color artwork. This was facilitated by digital image acquisition and processing performed by the authors.

    Optimization and standardization of images was performed by digital image engineering techniques to achieve an improvement in imagery over what is possible with conventional photomicrography. Our goal was to bring a new level of realism to the visual communication of concepts pertaining to microscopy.

    In some instances, visual content has been amplified by combining images from multiple microscopic fields into a single figure or showing different levels of magnification within the same figure. Digital image engineering also allows for image manipulation; an example is arrangement of cells that are randomized on a microscope field into a specific order to convey a concept such as cell maturation.

    We believe that the fidelity of visual imagery, as well as its liberal integration with text content, makes this work the first of its kind. Author team Contributing content and expertise to this project are a number of recognized authorities in the field of veterinary clinical pathology.

    These individuals have helped shape the existing curriculum, train the existing faculty, and create the disciplines of comparative laboratory medicine and diagnostic cytology as we know them today. It is through the combined efforts of so many experts in the field that this book was made possible. We hope you find this publication to be an excellent resource in the clinical laboratory and for laboratory data interpretation.

    Weiser and M. For the procedures and technologies likely to be employed within veterinary hospitals, general instructions and descriptions provide a review of the principles previously learned in laboratory courses. This, in conjunction with the instructions accompanying different devices and consumables, should enable users to reproduce the procedures to a satisfactory performance standard.

    For technologies more likely to be used only in large commercial or research laboratories, the overview provides familiarity with the basic principles. Hematologic techniques Basic techniques applicable for any veterinary hospital The procedures outlined here are most appropriate for the in-house veterinary laboratory in most practice settings. These procedures, with the exception of a cell counting hematology system, require minimal investment in instrumentation and technical training.

    These basic hematologic procedures include: Blood mixing for all hematologic measurements Packed cell volume or hematocrit by centrifugation Plasma protein estimation by refractometry Cell counting instrumentation Preparation of blood films Differential leukocyte count and blood film examination Blood mixing The blood sample is assumed to have been freshly and properly collected into an ethylenediaminetetraacetic acid EDTA tube as described in Chapter 2.

    When performing any hematologic procedure, it is important that the blood is thoroughly mixed.

    Cellular components may settle rapidly while the tube sits on a counter or in a tube rack Fig. As a result, failure to mix the sample before removing an aliquot for hematologic measurement may result in a serious error.

    Mixing can be performed by manually tipping the tube back and forth a minimum of times Fig. Alternatively, the tube may be placed on a rotating wheel or tilting rack designed specifically to mix blood Fig. Packed cell volume The packed cell volume value is the percentage of whole blood composed of erythrocytes.

    It is measured in a column of blood after centrifugation that results in maximal packing of the erythrocytes. Tools for performing the packed cell volume include mm tubes i. The procedure is performed using the following steps.

    First, the microhematocrit tube is filled via capillary action by holding it horizontally or slightly downward and then touching the upper end to the blood of the opened EDTA tube Fig. Hold the tube horizontally to prevent blood from dripping out of the tube, and seal one end by pressing the tube into the tube sealant once or twice Fig. Note that air may be present between the sealant and the blood Fig.

    This is not a problem, however, because the trapped air is removed during centrifugation. The tube is then loaded into the microhematocrit centrifuge according to the manufacturer s instructions Figs. The microhematocrit centrifuge is designed to spin the lightweight tube at very high speeds to generate sufficient centrifugal force to completely pack the red cells within 2 3 minutes. With such centrifugal force, most or all of the plasma is removed from the layers of packed cells.

    Allison, and Terry W. Gravity sedimentation of whole blood.

    A gentle, repetitive, back-and-forth tube inversion technique used to manually mix blood before removing aliquots for hematologic procedures. Figure 1. The tube should be positioned horizontally or tilted slightly downward to facilitate filling by capillary action.

    Capillary action is established by touching the upper end of the tube to the blood arrow. The surface holds several tubes on a ribbed rubber surface and tilts back and forth at the rate of oscillations per minute. Three distinct layers may be observed in the tube after removal from the centrifuge: the plasma column at the top, the packed erythrocytes at the bottom, and a small, middle white band known as the buffy coat Fig.

    The buffy coat consists of nucleated cells predominantly leukocytes and platelets, and it may be discolored red when the nucleated erythrocyte concentration is prominently increased.

    Observations of any abnormalities in the plasma column above the red cells should be recorded. Common abnormalities such as icterus, lipemia, and hemolysis are shown in Figure 1.

    Icterus is excessively yellow pigmentation of the Figure 1. Note that a small amount of air trapped between the blood and white clay is not a problem arrowhead in the inset. The observation of an icteric coloration to the plasma is diagnostically useful in small animals.

    It is not reliable in large animal species, however, because their serum usually has a yellow coloration from the normal carotene pigments associated with their herbivorous diet. The head and motor are designed to spin the tubes at very high speeds to achieve maximal erythrocyte packing.

    The tube on the left is normal. Note the packed erythrocytes at the bottom, plasma layer at the top, and buffy coat in the middle arrow; enlarged at left. The second tube illustrates lipemia, the third hemolysis, and the fourth icterus.

    Note also that the hematocrit is considerably decreased in the fourth tube. Two additional tubes illustrate buffy-coat abnormalities enlarged at right. The first of these tubes has an increased buffy coat that correlates with an increased leukocyte concentration. The second right is from a sheep with leukemia and has a dramatically increased buffy coat.

    There is also severe anemia. With such major abnormalities in cell concentration, separation of erythrocytes and leukocytes is not complete, and division may be blurred.
