What Does Globulin Mean in Dogs and Cats?
Quick answer
Globulins are a group of blood proteins that include antibodies. They often rise with chronic inflammation, infection, or immune activity, and occasionally with certain cancers. Low globulin can occur in very young animals or with protein loss. Vets look at globulin together with albumin and may run further protein tests.
What is Globulin?
Globulin is calculated as total protein minus albumin and includes antibodies.
Reference range
[Range pending sourced table] Reference ranges vary by lab and species. Use the range printed on your pet's report.
What can raise Globulin
- Chronic inflammation
- Infections
- Dental disease
- Some cancers
- Dehydration
What can lower Globulin
- Young age
- Protein loss
- Immune deficiency
Dogs vs cats
In dogs
Tick-borne infections can raise globulins in dogs.
In cats
High globulins in cats can accompany chronic infections or dental disease.
Why one value rarely tells the whole story
Globulin shows the immune system is active but not why. Hydration, recent meals, stress during the visit, medications, and how the sample was handled can all shift a result. Vets look at the whole panel, your pet's symptoms, and the trend across tests over time.
Conventional interpretation
Vets look for sources of inflammation and may run protein electrophoresis.
Whole-pet context
Dental health, skin, and ongoing infections are worth reviewing.
Supportive options are not a cure. Check with your veterinarian before adding any supplement.
Questions to ask your vet
- Could dental disease or infection explain this?
- Is protein electrophoresis needed?
- How does this compare with my pet's previous results?
Frequently asked questions
Can dental disease raise globulin?
- Yes, chronic dental inflammation is a common cause.
What is electrophoresis?
- A test that separates blood proteins to see which globulins are raised.
What is a normal Globulin range?
- Reference ranges vary by laboratory, analyzer, and species. Use the range printed on your pet's report and ask your vet how your pet's result compares.
Should Globulin be rechecked?
- Your veterinarian decides based on how far from range the value is, your pet's symptoms, and other results. Trends over time are often more useful than one result.
