Order Cortisol Levels Blood TestCortisol is a steroid hormone produced by the adrenal glands and released in response to signals from the pituitary gland. It influences how the body metabolizes carbohydrates, proteins, and fats, and it contributes to the regulation of blood pressure, immune activity, and the stress response. A cortisol levels blood test measures the concentration of this hormone in the bloodstream at the time the sample is collected.
About Cortisol Levels Blood Test in Sterling
Cortisol follows a daily rhythm, so the timing of a blood draw matters when interpreting results.
Cortisol is not released at a steady rate. Concentrations typically peak in the early morning and decline through the day, which is why the collection time is recorded alongside the result and why clinicians compare findings against time-specific reference ranges.
Because cortisol circulates partly bound to proteins and is cleared by the liver, a single measurement reflects only one moment in a continuously shifting pattern. Results are therefore evaluated in the context of symptoms, medical history, and sometimes additional testing such as urine or salivary cortisol collection.
The test is used to investigate suspected adrenal or pituitary disorders, including conditions in which cortisol is persistently high or persistently low. It is also monitored in people taking certain steroid medications that can suppress natural cortisol production. Preparation instructions from the laboratory should be followed, since factors such as the time of day and recent medication use can influence the reading.
