Use

The 17-Hydroxycorticosteroids, Urine test measures the level of 17-Hydroxycorticosteroids in urine. It is used to assess adrenal gland function and to diagnose disorders related to corticosteroid production. Elevated levels can be indicative of disorders such as Cushing's syndrome, adrenal hyperplasia, or adrenal tumors. This test is often part of the evaluation of patients with suspected adrenal insufficiency or hypercortisolism.

Limitations

Results should be interpreted with caution as factors like improper collection, incorrect pH adjustment, and inappropriate storage conditions may affect test outcomes. The test may not be suitable for patients with significant deviations in urine collection volume or duration from the standard 24-hour period, as this can impact the calculation of analyte levels per day. The lack of a reference interval for reported values necessitates careful interpretation by clinicians familiar with the patient's clinical condition and history.
