Cortisol Level Test
Check for Stress, Adrenal Health & Hormonal Imbalance
What Is a Cortisol Test?
A Cortisol Test measures the amount of cortisol in your blood. Produced by the adrenal glands, cortisol regulates:
- Energy production and metabolism
- Blood pressure control
- Immune system response
- Sleep-wake cycle
- Hormonal balance
Abnormal cortisol levels may indicate chronic stress, adrenal insufficiency, Cushing’s syndrome, or other hormone-related disorders.
At Regis Medical, your test includes:
- GP consultation to assess symptoms and medical history
- Quick blood draw (morning test recommended)
- Personalised results interpretation and treatment plan
Cortisol is your body’s main stress hormone, it is vital for energy, immunity, and hormonal balance. But when levels are too high or too low, it can lead to fatigue, mood changes, weight issues, and more.
Regis Medical GP clinic in Singapore offers accurate cortisol testing to assess adrenal gland function, detect hormonal imbalances, and guide personalised treatment. Whether you’re struggling with chronic stress, unexplained symptoms, or suspected adrenal disorders, this simple blood test can give you answers.
Why Check Your Cortisol Levels?
High or low cortisol can cause a wide range of symptoms:
High Cortisol (Hypercortisolism) – Often linked to stress, steroid medication, or Cushing’s syndrome.
Symptoms:
- Weight gain (especially around the abdomen or face)
- High blood pressure
- Insomnia
- Acne or oily skin
- Mood swings or anxiety
- Muscle weakness
- Slow wound healing
Low Cortisol (Hypocortisolism) – May be due to Addison’s disease or adrenal fatigue.
Symptoms:

- Low blood pressure and dizziness
- Salt cravings

- Darkening of the skin (Addison’s)
What Causes High or Low Cortisol Levels?
High Cortisol Levels may be caused by:
- Chronic stress or anxiety
- Long-term use of corticosteroid medications
- Cushing’s syndrome or adrenal tumours
- Severe illness or infection
- Depression or certain mental health disorders
Low Cortisol Levels may be caused by:
- Addison’s disease (adrenal insufficiency)
- Pituitary gland disorders (reduced ACTH production)
- Sudden withdrawal from long-term corticosteroid use

Identifying the cause is key to effective treatment, which is why a Doctor's assessment is essential.
