Cortisol Test – Private Testing in London
The Cortisol Test is available at South Kensington Medical and Dental, our CQC-registered clinic in South Kensington, London SW7. This test is priced at £66. A £50 phlebotomy fee applies per visit for blood collection. It requires a venous blood sample, and results are typically available within 1 day.
Cortisol is produced by the adrenal glands and regulates the stress response, metabolism, immune function, and blood pressure. Levels follow a diurnal rhythm, highest in the early morning.
Who Should Consider the Cortisol Test?
Individuals with suspected adrenal insufficiency (Addison's disease) or cortisol excess (Cushing's syndrome). Those experiencing chronic fatigue, unexplained weight changes, or blood pressure abnormalities.
Morning cortisol measured before 10 am is the standard screening approach. Very low or very high morning cortisol may warrant further dynamic testing such as a Synacthen test.
A trained nurse collects the blood sample by standard venepuncture, a straightforward procedure that typically takes around five minutes. Our clinic is on Old Brompton Road, directly opposite South Kensington tube station (Piccadilly, Circle, and District lines). No GP referral is needed — book online or call 020 7183 2362.
