Dog CBC / Chemistry

Analyte Reference Range Critical Low Critical High Notes
RBC 5.5-8.5 x10^6/uL 3.0 - Anemia concern if severe/acute drop
WBC 6.0-17.0 x10^3/uL 2.0 40.0 Interpret with differential and left shift
Platelets 200-500 x10^3/uL 50 - Severe thrombocytopenia = bleeding risk
Glucose 75-120 mg/dL 45 450 Very high values suggest DKA/HHS risk
BUN 7-27 mg/dL - 100 Interpret with creatinine and hydration
Creatinine 0.5-1.8 mg/dL - 7.0 Rapid trend is clinically important
Sodium 140-155 mmol/L 125 170 Neurologic risk if severe derangement
Potassium 3.5-5.8 mmol/L 2.5 7.0 ECG monitoring if high
ALT 10-125 U/L - 1000 Leakage enzyme; assess trend and context
Total Bilirubin 0.1-0.6 mg/dL - 3.0 Icterus usually visible when elevated

Cat CBC / Chemistry

Analyte Reference Range Critical Low Critical High Notes
RBC 5.0-10.0 x10^6/uL 3.0 - Assess regeneration with reticulocytes
WBC 5.5-19.5 x10^3/uL 2.0 40.0 Stress leukogram can alter interpretation
Platelets 300-800 x10^3/uL 50 - Check for clumping before diagnosis
Glucose 70-150 mg/dL 45 450 Stress hyperglycemia is common
BUN 14-36 mg/dL - 100 Trend with creatinine/USG
Creatinine 0.8-2.4 mg/dL - 7.0 Evaluate for AKI vs CKD
Sodium 145-158 mmol/L 130 170 Rapid shifts can be dangerous
Potassium 3.5-5.3 mmol/L 2.5 7.0 Critical in urethral obstruction
ALT 20-100 U/L - 800 Interpret with ALP and bilirubin
Phosphorus 3.0-6.5 mg/dL 1.5 10.0 Elevated with renal disease/obstruction

Ranges vary by lab analyzer and protocol. Always use your laboratory's reference intervals for patient care decisions.
