Clinical Veterinary Pathology, Hematology, and Serum Biochemistry Interpretation

Diagnostic laboratory testing is the cornerstone of modern internal veterinary medicine. Because companion animals cannot verbalize pain, routine Complete Blood Count (CBC), Serum Chemistry Panels, and Urinalysis provide an objective window into cellular oxygen transport, immune activation, liver function, and renal filtration.

Under reference standards established by the American Society for Veterinary Clinical Pathology (ASVCP) and the Merck Veterinary Manual:

Core Diagnostic Blood Testing Panels:
1. Complete Blood Count (CBC):
   - RBC & HCT / PCV: Hematocrit (Normal dog: 37–55%, cat: 30–45% - Low = Anemia)
   - WBC: White Blood Cells (Elevated = Infection, inflammation, or leukemia)
   - PLT: Platelets (Thrombocytes - Critical for primary blood clotting)
2. Comprehensive Chemistry Profile (Chem 17 / Chem 24):
   - Renal Function: BUN (Blood Urea Nitrogen), Creatinine, and SDMA (Early kidney marker)
   - Hepatic Function: ALT (Liver cell damage), ALKP / ALP (Biliary stasis), Bilirubin
   - Endocrine / Metabolic: Blood Glucose, Albumin, Total Protein, Phosphorus, Calcium

The Breakthrough of SDMA Early Renal Detection

Traditional serum Creatinine does not elevate until 75% of functional kidney nephrons are permanently destroyed. Modern veterinary panels now include Symmetric Dimethylarginine (SDMA), a sensitive biomarker that detects renal decline when only 25% to 40% of kidney function is lost, allowing therapeutic dietary interventions years earlier.
