The Human Cortisol ELISA Kit is widely used in clinical diagnostics to measure cortisol levels in serum, plasma, urine, and saliva samples. It is essential for assessing adrenal gland function and diagnosing conditions such as Cushing's syndrome, Addison's disease, and other endocrine disorders. Researchers also utilize this kit in studies related to stress, circadian rhythms, and the impact of cortisol on metabolic and immune responses. In pharmaceutical development, it helps evaluate the efficacy of drugs targeting cortisol regulation. The kit's high sensitivity and specificity make it a reliable tool for both diagnostic and research purposes.
