Testing is essential to evaluate patients with fever, vomiting, diarrhea, weakness, pale gums, and/or appetite loss, or receiving anesthesia. Testing information and some conditions which each may indicate are identified below:

  • Red Blood Cell Count (RBC): anemia, red blood cell disorders
  • Hemoglobin: different anemias
  • PCV (packed cell volume or hematocrit): anemia, dehydration
  • White Blood Cell Count (WBC): certain diseases, infections, inflammation
  • Neutrophils/Lymphocytes/Monocytesinfection, stress, cancer, hormonal imbalance, other conditions
  • Eosinophilsallergic or parasitic conditions
  • Platelet: blood clotting ability or disorders
  • Reticulocytesrebuilding of red blood cell numbers
