Cortisol ELISA kits are assays designed to detect the glucocorticoid hormone cortisol. Produced mainly in the adrenal gland, the secretion of cortisol is controlled by adrenocorticotrophic hormone (ACTH) and corticotrophin-releasing hormone (CRH). It is known as a ‘stress hormone’ as its levels fluctuate when the body undergoes stress. It is found in the blood in 3 forms – free cortisol, protein-bound, and cortisol metabolites. Cortisol is involved in gluconeogenesis, lipolysis, bone formation, and immune responses. Cortisol ELISA kits can be used to study stress responses, metabolic processes, and metabolic disorders.
