In the occasional case with no elevation of catecholamines, a 24-hour urine collection is necessary. Urine catecholamines must be measured before surgical removal of the tumor or before initiation of therapy. Catecholamine secretion can be used not only as a diagnostic aid but also as a means ...
Catecholamine excretion, when corrected for creatinine excretion, decreases throughout childhood, reaching adult levels at age 15. To explore the hypothesis that the pubertal process may play a role in this decrease we measured catecholamine and vanillylmandelic acid (VMA) excretion in 24 hour urine ...

This is a rare case of a symptomatic pheochromocytoma without elevated urine catecholamines and metanephrines. According to the literature, plasma free metanephrines would be the ideal test for biochemical detection of the tumor. However, in the event that they are not available and there is a ...
Exclusion criteria included self-reported past or present major medical or psychiatric illness, positive urine drug screens, a score of 10 or greater on the BDI, regular tobacco use, ingestion of more than three cups of coffee (or the equivalent) per day, or atypical sleeping patterns (...
Resting plasma and 24-hour urine samples were collected periodically throughout the duration of the study. Further, subjects participated in submaximal exercise tests (50 minutes at 50% sea level maximum oxygen consumption [Vo2max]) at Sea level and on days 1 and 12 at altitude. Urinary ...
Participants (193 healthy adults) provided 24-hr urine samples that were collected in a controlled environment (hotel), and divided into 9-hr daytime and 15-hr overnight collections. On the same day, resting blood pressure (BP) was measured, and 8 samples of salivary Cortisol were collected....

(hypertension), headache, tachycardia, excessive sweating while at rest, the development of symptoms after suddenly rising from a bent-over position, and anxiety attacks. Abdominal imaging and 24 hour urine collection for catecholamines are usually sufficient for diagnosis. Catecholamine blockade with ...
