Feline Cortisol (fCOR) Test Kit

Cortisol is a type of glucocorticoid secreted by the adrenal cortex and plays an important physiological role in cats. It is involved in regulating various physiological processes such as metabolism, immune response, and stress response.

The cortisol level in cats can be influenced by multiple factors, such as circadian rhythm, stress state, and diseases. Under normal circumstances, the cortisol level in cats fluctuates to a certain extent throughout the day, usually being higher in the morning and lower in the evening.

Clinical application:

Diagnosis of Hyperadrenocorticism (Cushing's Syndrome):

When cats present with symptoms such as polydipsia, polyuria, abdominal enlargement, and symmetrical hair loss, testing cortisol levels is helpful for diagnosing Cushing's syndrome. If the cortisol level continuously rises and loses the normal circadian rhythm, it might suggest excessive secretion of cortisol by the adrenal cortex.

For example, an obese cat shows symptoms such as thinner skin, susceptibility to infection, and muscle weakness. The detection of fCOR reveals a significantly elevated level. Combined with other examination results, it is diagnosed as Cushing's syndrome.

Diagnosis of Hypoadrenocorticism (Addison's Disease):

Cats with Addison's disease have insufficient cortisol secretion. By detecting the fCOR level being lower than the normal range and combining with clinical symptoms and other related examinations, a diagnosis can be made.
