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 hormonal imbalances. In research, it helps study stress responses, circadian rhythms, and the impact of cortisol on various physiological processes. The kit is also employed in pharmaceutical development to evaluate the efficacy of drugs targeting cortisol regulation. Its high sensitivity and specificity make it a reliable tool for both diagnostic and experimental purposes.
