Lab values by body system
Reference ranges vary by lab and species — always compare with the range printed on your pet's report.
Liver
Enzymes and pigments that reflect liver cells and bile flow.
- ALTalanine aminotransferase
An enzyme that may rise when liver cells are irritated.
- ALPalkaline phosphatase
An enzyme influenced by the liver, bile flow, growth, and some medications.
- ASTaspartate aminotransferase
An enzyme from liver and muscle that adds context to ALT.
- GGTgamma-glutamyl transferase
An enzyme linked to bile flow, read alongside ALP.
- Total Bilirubin
A yellow pigment that builds up with liver, bile, or red cell problems.
Kidneys
Markers of how well the kidneys filter waste and balance minerals.
- Creatinine
A waste product used alongside other markers to understand kidney filtration.
- BUNblood urea nitrogen
A nitrogen waste marker affected by kidneys, hydration, and diet.
- SDMAsymmetric dimethylarginine
An early kidney marker less affected by muscle mass.
- Phosphorus
A mineral the kidneys balance; often watched in kidney care.
Immune and white blood cells
Cells that respond to infection, inflammation, allergy, and stress.
- Eosinophils
White blood cells that can rise with allergies, parasites, or inflammation.
- WBCwhite blood cell count
The total count of infection- and inflammation-fighting cells.
- Neutrophils
First-responder white cells that rise with infection and stress.
- Lymphocytes
Immune memory cells that often dip with stress.
- Monocytes
Clean-up white cells linked to longer-lasting inflammation.
- Basophils
Rare white cells involved in allergy and parasite responses.
Metabolic
Blood sugar and fats, read alongside meals, weight, and hormones.
Red blood cells and platelets
Oxygen-carrying cells and the cells that help blood clot.
Electrolytes and minerals
Salts and minerals that support hydration, nerves, and muscles.
Thyroid
Hormones that set the body's metabolic pace.
Proteins, pancreas and others
Blood proteins and pancreatic enzymes.
- Albumin
The main blood protein, made by the liver.
- Total Protein
Albumin plus globulins, reflecting hydration and inflammation.
- Globulin
Immune and transport proteins that rise with inflammation.
- Amylase
A digestive enzyme with limited value for pancreatitis on its own.
- Lipase
A pancreatic enzyme used when pancreatitis is suspected.
