What does it mean if a cat has high ESR? - briefly
A high ESR (erythrocyte sedimentation rate) in a cat typically indicates inflammation, infection, or an underlying disease process affecting the body. Further diagnostic tests are usually required to identify the specific cause.
What does it mean if a cat has high ESR? - in detail
A high erythrocyte sedimentation rate (ESR) in a cat indicates an increased rate at which red blood cells settle at the bottom of a test tube over a specified period, typically one hour. This elevation is a non-specific marker of inflammation or other underlying conditions affecting the body. In cats, a high ESR can suggest the presence of infections, autoimmune diseases, chronic inflammatory disorders, or even certain types of cancer. It may also be associated with tissue damage, trauma, or systemic illnesses such as feline infectious peritonitis (FIP) or kidney disease. While ESR alone does not diagnose a specific condition, it serves as a valuable indicator that further diagnostic investigations, such as blood tests, imaging, or biopsies, are necessary to identify the root cause. Factors such as age, stress, or concurrent health issues can also influence ESR levels, so results must be interpreted alongside clinical signs and other laboratory findings. Prompt veterinary attention is essential to address the underlying condition and ensure appropriate treatment for the cat’s health and well-being.
