(urine and/or serum)

A 24-hour urine specimen was collected for analysis of catecholamines and catecholamine metabolites. Plasma catecholamines were also assayed. 
                                            Patient       Reference
Norepinephrine, Free (24 hr U)              1800 ug       15 - 80
Epinephrine, Free (24 hr U)                  100 ug        0 - 20
Vanillylmandelic acid (VMA, 24 hr U)        12.5 mg         2 - 7
Metanephrines (24 hr U)                      2.5 mg          <1.0

Catecholamines (P)
    Norepinephrine                          2500 pg/ml  174 - 624
    Epinephrine                               85 pg/ml    0 - 114
