Total protein is elevated in a biochemical blood test, what does this mean for a dog? - briefly
Elevated total protein levels in a dog's biochemical blood test can indicate dehydration or an increase in globulins due to inflammation or infection. It is essential to consult with a veterinarian for further evaluation and appropriate treatment.

Elevated total protein levels in a biochemical blood test can indicate several underlying conditions in dogs. Total protein comprises two main fractions: albumin and globulins. Albumin is produced by the liver, while globulins are predominantly synthesized by immune cells. An increase in total protein can be driven by changes in either or both of these fractions.
Albumin, being a negative acute-phase protein, typically decreases during inflammation or infection. However, globulin levels often rise due to their role as positive acute-phase proteins. This means that an elevated total protein level is commonly associated with conditions such as inflammation, infection, or immune system activation.
Inflammatory diseases like arthritis, pancreatitis, and autoimmune disorders can lead to increased globulin levels, thereby raising the total protein count. Similarly, infections caused by bacteria, viruses, or parasites can also result in a rise in globulins. Chronic kidney disease, which is common in older dogs, may cause an increase in total protein due to the body's attempt to maintain fluid balance by retaining proteins.
Dehydration can also contribute to elevated total protein levels. When a dog is dehydrated, the volume of plasma decreases while the concentration of proteins remains relatively constant, leading to an apparent increase in total protein. This is why it is essential for veterinarians to consider hydration status when interpreting biochemical blood test results.
To accurately diagnose the underlying cause of elevated total protein levels, veterinarians often perform additional tests. These may include a complete blood count (CBC) to assess white blood cell numbers and types, which can indicate infection or inflammation. Serum electrophoresis is another useful tool that separates proteins into their specific fractions, providing more detailed information about the distribution of albumin and globulins.
In summary, elevated total protein levels in a dog's biochemical blood test can signal various health issues, including inflammation, infection, immune system activation, kidney disease, or dehydration. A thorough evaluation, considering the clinical signs and results of other diagnostic tests, is crucial for determining the exact cause and developing an appropriate treatment plan.
