| Interpretive Data: |
Interpretive Data: The optimal specimen for this testing is a 24-hour urine collection. Mass per day calculations are not reported for the following specimen types: a random collection, a collection with duration of less than 20 hours, a collection with duration of greater than 28 hours, or a collection with total volume less than 400 mL. Ratios to creatinine may be useful for these evaluations.
Baseline urinary free cortisol excretion less than 5 ug/d may be consistent with adrenal insufficiency.
