How to Use Normal Values During Study

Confirm the species-specific interval first (dog vs cat differences are meaningful).
Interpret abnormalities in context: signalment, hydration status, and trend over time.
Link critical abnormalities to stabilization priorities before broad differential expansion.

Quick Reference Snapshot

Parameter	Typical Dog Range	Typical Cat Range	How to Use It
Hematocrit (PCV)	37-55%	30-45%	Pair with hydration status before labeling anemia severity.
Creatinine	0.5-1.8 mg/dL	0.8-2.4 mg/dL	Trend over time and compare with urine concentration.
Potassium	3.5-5.8 mmol/L	3.4-5.6 mmol/L	Prioritize ECG risk if marked hypo/hyperkalemia is present.
Glucose	75-120 mg/dL	70-150 mg/dL	Interpret with stress context, especially in cats.

Intervals vary by analyzer and lab. Use this table for orientation, then confirm with your lab-specific reference interval.

Species Differences and Variability Warnings

Cats can show stress hyperglycemia, so glucose values need context before endocrine conclusions.
Breed, age, and body condition can shift baseline expectations, especially for creatinine and liver enzymes.
Single values can mislead when fluid shifts or sampling artifacts are present.

When to Escalate Immediately

Rapidly rising lactate, severe electrolyte derangement, or worsening acid-base status.
Marked anemia with perfusion compromise or active bleeding signs.
Respiratory distress, syncope, altered mentation, or arrhythmia alongside abnormal labs.
