PTS Pod Cortisol

This is a PROFESSIONAL product ONLY. It is not meant to be used by consumers.

The PTS Pod system offers a variety of different lab-based tests. Cortisol is a hormone that plays a role in the metabolism of proteins, lipids, and carbohydrates, among other functions. Normally, the level of cortisol in the blood rises and falls in a "diurnal variation" pattern, peaking early in the morning, then declining throughout the day and reaching its lowest level about midnight.

When is it ordered?

A cortisol test may be ordered when a person has symptoms that suggest a high level of cortisol and Cushing syndrome, such as:

  • High blood pressure (hypertension)
  • High blood sugar (glucose)
  • Obesity, especially in the trunk
  • Fragile skin
  • Purple streaks on the abdomen
  • Muscle wasting and weakness
  • Osteoporosis
Testing may be ordered when women have irregular menstrual periods and increased facial hair; children may have delayed development and a short stature.

This test may be ordered when someone has symptoms suggestive of a low level of cortisol, adrenal insufficiency or Addison disease, such as:

  • Weight loss
  • Muscle weakness
  • Fatigue
  • Low blood pressure
  • Abdominal pain
  • Dark patches of skin (this occurs in Addison disease but not secondary adrenal insufficiency)

Sometimes decreased production combined with a stressor can cause an adrenal crisis that can be life-threatening and requires immediate medical attention. Symptoms of a crisis may include:

  • Sudden onset of severe pain in the lower back, abdomen, or legs
  • Vomiting and diarrhea, resulting in dehydration
  • Low blood pressure (hypotension)
  • Loss of consciousness
Suppression or stimulation testing is ordered when initial findings are abnormal. Cortisol testing may be ordered at intervals after a diagnosis of Cushing syndrome or Addison disease to monitor the effectiveness of treatment.

Is there anything else I should know?

Similar to those with adrenal insufficiency, people with a condition called congenital adrenal hyperplasia (CAH) have low cortisol levels and do not respond to ACTH stimulation tests. Cortisol measurement is one of many tests that may be used to help evaluate a person for CAH.

Heat, cold, infection, trauma, exercise, obesity, and debilitating disease can influence cortisol concentrations. Pregnancy, physical and emotional stress, and illness can increase cortisol levels. Cortisol levels may also increase as a result of hyperthyroidism or obesity. A number of drugs can also increase levels, particularly oral contraceptives (birth control pills), hydrocortisone (the synthetic form of cortisol), and spironolactone.

Adults have slightly higher cortisol levels than children do.

Hypothyroidism may decrease cortisol levels. Drugs that may decrease levels include some steroid hormones.

Salivary cortisol testing is being used more frequently to help diagnose Cushing syndrome and stress-related disorders but still requires specialized expertise to perform.
