Cortisol, Serum (Morning Sample) Test near me in Ernakulam









The Cortisol, Serum (Morning Sample) Test is a blood test that measures the level of cortisol, a steroid hormone produced by the adrenal gland. It is typically done in the morning when cortisol levels are at their peak, helping diagnose conditions such as Cushing syndrome and Addison’s disease which can lead to either too much or too little production of cortisol. Additionally, it helps evaluate how well the pituitary and adrenal glands are working. This test is widely available at an affordable price with Tata 1mg labs in Ernakulam.
Your doctor will likely have you do the test early in the morning because cortisol levels fluctuate throughout the day, influenced by the body’s circadian rhythm. You may be asked not to do any vigorous exercise the day before the test.








What does Cortisol, Serum (Morning Sample) Test measure?
The Cortisol, Serum (Morning Sample) Test test measures the levels of the cortisol hormone in the blood. Cortisol is a vital hormone produced by the adrenal glands in response to stress and plays an important role in various bodily functions such as metabolism, immune response, and the body’s stress response system.
This test is conducted during the morning because cortisol levels fluctuate throughout the day, typically peaking in the early morning and gradually declining throughout the day and then into the evening. By measuring the cortisol levels in the morning, the doctors can assess the body’s natural rhythm (circadian rhythm) and evaluate how well the adrenal glands and pituitary glands are working. Deranged cortisol levels can indicate conditions such as adrenal insufficiency (Addison’s disease), cortisol excess (Cushing’s syndrome), or other disorders affecting these glands. Additionally, this test helps diagnose and monitor conditions related to stress, sleep disorders, metabolism, and overall hormone balance.
