Answer:
On the morning of the 24-hour cortisol urine test, a person will need to get up and empty their bladder into the toilet, noting the time.
From then on, they collect all the urine they produce for the rest of the day in the container the doctor provides.
People can use a small container or device, such as a toilet hat, to collect urine samples, and then carefully empty them into the larger collection container.
People should try not to get anything other than urine in the collection unit, such as feces or menstrual blood.
After 24 hours, they have to urinate one final time and add this urine to the collection. Again, they must note the time.
Some collection containers need to be refrigerated during the entire 24-hour collection period. A person will need to follow the hospital staff's instructions in this respect.
People should take the collection container to a doctor's office, hospital, or laboratory, as soon as they can after completing the test. Whoever receives the collection container will ask for the start and end times of the test.
People may need to repeat the test several times to make sure the results are accurate. A doctor may also recommend additional tests, such as blood tests, salivary tests, or dexamethasone suppression tests.
