Reference hematologic values and morphologic features of blood cells in healthy adult llamas

Abstract

Hematologic values and cellular morphologic features were evaluated for 38 healthy adult llamas. Reference ranges were determined for PCV, reticulocyte concentration, leukocyte concentration, and leukocyte differential counts. The approach used in this study was to focus on hematologic values that may be determined by use of techniques readily available to the practicing veterinarian and nonveterinary laboratory. Unique cellular morphologic features commonly observed and interpreted as normal included large granular lymphocytes, hyposegmented eosinophil nuclei, folded erythrocytes, and hemoglobin crystals.
