Why is albumin elevated in cats? - briefly
Elevated albumin in cats often indicates dehydration or a response to inflammation, as albumin levels can rise due to reduced fluid volume or as part of an acute-phase reaction.
Why is albumin elevated in cats? - in detail
Albumin, a major protein synthesized by the liver, is essential for maintaining oncotic pressure and transporting various substances in the bloodstream. Elevated albumin levels in cats, known as hyperalbuminemia, are relatively uncommon but can occur due to several physiological or pathological factors. Dehydration is one of the most common causes, as reduced fluid volume in the body leads to hemoconcentration, increasing the relative concentration of albumin in the blood. This condition can result from inadequate water intake, excessive fluid loss through vomiting, diarrhea, or increased urination. Chronic inflammation or infections may also elevate albumin levels, as the liver increases protein production in response to systemic stress. Certain metabolic disorders, such as hyperthyroidism or diabetes mellitus, can contribute to elevated albumin by altering protein metabolism or causing secondary dehydration. Additionally, laboratory errors or sample handling issues, such as hemolysis or prolonged storage, may artifactually increase albumin measurements. While elevated albumin alone is not diagnostic of a specific disease, it often indicates an underlying condition that requires further investigation. A comprehensive evaluation, including a complete blood count, serum biochemistry, and urinalysis, is necessary to identify the root cause and guide appropriate treatment. Monitoring hydration status and addressing any concurrent illnesses are critical steps in managing hyperalbuminemia in cats.
