VITAMIN B12; CYANOCOBALAMIN

Description

Vitamin B12 (Cyanocobalamin) Blood Test for Dogs & Cats

The Vitamin B12 (Cyanocobalamin) blood test measures the concentration of cobalamin in your pet’s serum. Vitamin B12 is an essential water-soluble vitamin that plays a critical role in DNA synthesis, red blood cell formation, neurological function, and metabolic processes. In dogs and cats, B12 deficiency is commonly associated with gastrointestinal diseases, particularly those affecting the small intestine and pancreas, where B12 absorption takes place.

Why Is This Test Important?

Cobalamin deficiency in pets is more common than many pet owners realize. It is most frequently seen alongside conditions such as inflammatory bowel disease (IBD), exocrine pancreatic insufficiency (EPI), chronic enteropathy, and small intestinal bacterial overgrowth (SIBO). Without adequate B12, affected pets may experience poor appetite, weight loss, lethargy, chronic diarrhea, and failure to thrive. Regular monitoring is essential for managing and treating these conditions effectively.

When Is This Test Recommended?

• Dogs or cats with chronic diarrhea or vomiting
• Suspected inflammatory bowel disease (IBD) or chronic enteropathy
• Pets with exocrine pancreatic insufficiency (EPI)
• Unexplained weight loss or poor body condition
• Lethargy, weakness, or neurological signs
• Follow-up monitoring for pets receiving B12 supplementation

Normal Reference Ranges

In cats, the reference interval for serum cobalamin is typically 290–1,500 ng/L. Dogs generally have similar reference ranges, though laboratory-specific values may vary. Low cobalamin levels indicate deficiency requiring supplementation, while very high levels may suggest certain disease conditions and warrant veterinary consultation.

Understanding Your Results

Low serum B12 levels indicate deficiency and usually require parenteral (injectable) or oral supplementation. Your veterinarian will also investigate the underlying cause of deficiency to ensure complete treatment. Rechecking B12 levels after supplementation helps confirm treatment response.
