Overview of the Urine Cortisol Test

The Urine Cortisol Test measures Free Cortisol (Urine), a hormone produced by the adrenal glands that plays an important role in the body's response to stress, metabolism, blood pressure regulation and immune function. Measuring cortisol in urine provides an assessment of the amount of free (unbound) cortisol excreted over the collection period.

This is a single-biomarker adrenal hormone test that measures Free Cortisol (Urine). It is commonly requested when investigating suspected changes in cortisol production or monitoring adrenal function as part of a wider endocrine assessment. Depending on the clinical indication, this test may be performed alongside blood or saliva cortisol measurements and other hormone investigations.

People may choose this test if they have symptoms that may be related to cortisol imbalance or if their GP, endocrinologist or other healthcare professional has recommended further adrenal hormone assessment.

The Urine Cortisol Test provides valuable laboratory information but does not diagnose or exclude an endocrine disorder on its own. Results should always be interpreted alongside symptoms, medical history, medications and any additional laboratory or imaging investigations.

What Does the Urine Cortisol Test Check ?

Adrenal Hormone Marker

Free Cortisol (Urine) - measures biologically active cortisol excreted in urine during the collection period. It helps assess overall cortisol production and adrenal function.

Who May Benefit From the Urine Cortisol Test?

This test may be suitable for people who want to:

Assess cortisol production as part of an adrenal hormone evaluation.

Investigate symptoms that may be associated with changes in cortisol levels.

Support investigations recommended by an endocrinologist or GP.

Monitor adrenal function where repeat testing has been advised.

Complement blood or saliva cortisol testing.

Monitor known endocrine conditions under clinical supervision.

Take a proactive approach to hormone health.

Obtain additional laboratory information before a specialist consultation.

Review cortisol levels as part of a broader endocrine workup.

Arrange a private hormone test in London without waiting for a GP referral.

Symptoms and Reasons to Consider the Urine Cortisol Test

You may wish to consider the Urine Cortisol Test if you are experiencing symptoms or concerns that may be linked with adrenal hormone function. This test may be relevant if you have:

Persistent tiredness or fatigue that does not improve with rest.

Unexplained weight changes, including gain or loss, without a clear cause.

High blood pressure requiring further investigation, especially if it is difficult to control.

Muscle weakness or reduced exercise tolerance that affects daily activities.

Changes in blood sugar control, such as unexplained highs or lows.

Easy bruising or slower-than-usual healing after minor knocks or cuts.

Persistent stress-related symptoms requiring clinical assessment, such as anxiety, poor sleep or feeling overwhelmed.

Monitoring of adrenal hormone disorders, a recommendation from your GP or endocrinologist, or a need for specialist endocrine investigations.

Cortisol influences many important functions throughout the body, including metabolism, immune responses and the body's normal stress response. Measuring urinary free cortisol provides additional laboratory information that may contribute to a wider endocrine assessment.

Symptoms associated with altered cortisol levels can have many different causes. Results should always be interpreted alongside symptoms, medical history, medications, the timing and completeness of the urine collection, and professional medical advice.
