The Cortisol (Random Sample) Serum Test measures the level of cortisol, often referred to as the stress hormone in the bloodstream. Produced by the adrenal glands, cortisol plays a crucial role in regulating metabolism, blood pressure, immune response, and the body’s response to stress. Abnormal cortisol levels can indicate adrenal gland disorders, such as Addison’s disease or Cushing’s syndrome, and can affect overall health by causing fatigue, weight changes, or blood pressure irregularities.

The Cortisol Test is particularly valuable for individuals experiencing symptoms of adrenal imbalance, including unexplained fatigue, weight changes, muscle weakness, or abnormal blood pressure. Elevated cortisol levels may suggest conditions like Cushing’s syndrome, while low levels could indicate Addison’s disease. Since cortisol levels naturally fluctuate throughout the day, the Random Sample Test provides a convenient snapshot, assisting doctors in identifying hormonal imbalances and supporting the diagnosis of adrenal gland disorders.
