Cortisol (FIA)

A Cortisol test measures the level of the stress hormone in your blood, urine, or saliva to help diagnose disorders of the adrenal or pituitary glands. It is incredibly helpful because cortisol plays a massive role in regulating your metabolism, reducing inflammation, and managing blood pressure. If your levels are chronically too high or too low, it can lead to serious health issues like Cushings syndrome (excess cortisol) or Addisons disease (cortisol deficiency). By pinpointing these imbalances early, the test allows healthcare providers to treat the root cause of symptoms like unexplained fatigue, high blood pressure, muscle weakness, or rapid weight changes, ultimately helping restore your internal balance.
