Special instructionsDo not take biotin supplements for 2 days prior to this test. If you are taking prescribed biotin you should discuss this with your doctor. HRT and the contraceptive pill can affect the results of this test, taking the test during a break from these will give more accurate results. Your result could be affected by corticosteroid medication (e.g. prednisolone). Ask your doctor whether you should stop before testing. Take care to collect all the urine that you pass in 24 hours in the container.
A cortisol urine test tends to be more comprehensive than any other cortisol test as it measures the total amount of cortisol excreted into the urine over a 24-hour period whereas blood or saliva tests only measure cortisol levels at a particular time of day. Some people also find blood tests to be stressful and since the body releases more cortisol during times of stress, the results may be affected.
This test establishes the levels of cortisol in the urine and can help identify Cushing's syndrome, which is caused by too much cortisol, or Addison's disease, which is caused by damage to the adrenal glands and is associated with too little cortisol.
Why take this test?
- You want to investigate to see whether you could have Cushing's syndrome or Addison's disease
- You are worried your stressful lifestyle is damaging your health
