A 24-hour urine for cortisol is the initial laboratory test ordered to evaluate for hypercortisolism. This test measures the amount of cortisol excreted in the urine over a 24-hour period and is considered the most reliable test for evaluating excess cortisol production. Serum sodium and potassium levels and fasting blood glucose levels may also be ordered as part of the evaluation, but they are not the initial tests ordered.
