What Does Total Protein Mean in Dogs and Cats?
Quick answer
Total protein measures all proteins in the blood, mainly albumin and globulins. High total protein often reflects dehydration or inflammation, while low levels can come from protein loss, liver problems, or poor nutrition. Looking at albumin and globulin separately usually explains why total protein has changed.
What is Total Protein?
Total protein is the sum of albumin and globulins in the blood.
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 Total Protein
- Dehydration
- Chronic inflammation or infection
- Some cancers
What can lower Total Protein
- Protein loss through kidneys or gut
- Liver dysfunction
- Blood loss
- Poor nutrition
Dogs vs cats
In dogs
Young dogs have slightly lower total protein than adults.
In cats
Cats with chronic inflammation can show raised total protein from globulins.
Why one value rarely tells the whole story
Total protein is most useful when split into albumin and globulin. 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 interpret total protein with albumin, globulin, and hematocrit.
Whole-pet context
Hydration, appetite, and weight changes help put this in context.
Supportive options are not a cure. Check with your veterinarian before adding any supplement.
Questions to ask your vet
- Is the change from albumin or globulin?
- Could dehydration explain this?
- How does this compare with my pet's previous results?
Frequently asked questions
Does high total protein mean too much protein in food?
- No. Blood protein is not directly set by dietary protein.
Why compare with hematocrit?
- Both rise with dehydration, which helps vets interpret them.
What is a normal Total Protein 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 Total Protein 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.
