Cortisol Blood Test in Epsom – Monitor Stress Levels and Adrenal Function
The Cortisol Blood Test is a valuable tool for assessing your stress levels and adrenal function. Cortisol, known as the “stress hormone,” is produced by the adrenal glands and plays a crucial role in regulating metabolism, immune response, and stress reactions. Abnormal cortisol levels can indicate stress, adrenal issues, or underlying health conditions.
Why Choose the Cortisol Blood Test in Epsom?
If you're experiencing symptoms like fatigue, insomnia, weight gain, or anxiety, a Cortisol Blood Test can help determine if cortisol imbalances are affecting your health. Elevated cortisol levels are often linked to chronic stress, while low levels may be a sign of adrenal insufficiency or Addison’s disease.
This test is ideal for individuals who are:
- Experiencing chronic stress or anxiety.
- Struggling with fatigue, insomnia, or difficulty managing stress.
- Concerned about adrenal health or hormonal imbalances.
- Managing conditions like Cushing’s syndrome or Addison’s disease.
By measuring cortisol levels in the blood, the test provides insight into your adrenal gland function and can help guide treatment for stress management and other related conditions.
What’s Included in the Cortisol Blood Test?
The Cortisol Blood Test measures the concentration of cortisol in your blood at specific times of day. Cortisol follows a diurnal pattern, meaning levels are typically highest in the morning and decrease throughout the day. This test can help assess your body's cortisol rhythm and determine if an imbalance is affecting your health.

Frequently Asked Questions
What does a cortisol blood test show?
A cortisol blood test measures the level of cortisol, a hormone produced by your adrenal glands that helps regulate stress, metabolism, and energy levels. It helps identify adrenal gland disorders, stress-related conditions, and hormonal imbalances.
Why is cortisol important?
Cortisol plays a key role in how your body responds to stress, maintains blood sugar levels, and supports metabolism and immunity. Abnormal levels can indicate Cushing’s syndrome (high cortisol) or Addison’s disease (low cortisol).
What are the symptoms of high cortisol levels?
High cortisol may cause weight gain (especially around the abdomen or face), fatigue, mood swings, sleep problems, and high blood pressure. Persistent high levels can increase the risk of diabetes, anxiety, or heart disease.
What are the symptoms of low cortisol levels?
Low cortisol can cause extreme tiredness, low blood pressure, muscle weakness, weight loss, and mood changes. This may be a sign of adrenal insufficiency or other hormone-related conditions.
When is the best time to get a cortisol blood test?
The best time to test cortisol is in the morning (around 9 AM), when levels are naturally at their peak. Testing at this time gives the most accurate picture of your adrenal function.
Do I need to fast before a cortisol blood test?
Fasting isn’t always required, but it’s best to avoid eating or drinking anything except water for 6–8 hours before your test to ensure consistency in your results.
How long do results take?
Results for the Cortisol Blood Test in Epsom are available next working day, sent securely by email with a text message password for private access.
Who should consider a cortisol test?
You may benefit from this test if you experience chronic stress, unexplained fatigue, weight changes, sleep problems, or mood swings. It’s also useful for those undergoing long-term steroid treatment or being investigated for adrenal disorders.
