Key result
Exposure to the Stroop mental performance test significantly increased both urinary and plasma adrenaline, with a mean intraindividual plasma/urine correlation of r=0.70 (p<0.001).

Urinary adrenaline may proxy plasma changes under mental stress; leaves open validation in clinical cohorts.
Does mental stress alter urinary and plasma catecholamine levels in human subjects?
Effect estimate: r = 0.70
p-value: p=<0.001
Both urinary and plasma adrenaline are useful indicators of sympatho-adrenal activity changes during mental stress, showing significant correlation.
Åkerstedt et al. (1983) studied this question. Stroop mental performance test vs. rest periods was evaluated on intraindividual plasma/urine correlation for adrenaline (r = 0.70, p=<0.001). Exposure to the Stroop mental performance test significantly increased both urinary and plasma adrenaline, with a mean intraindividual plasma/urine correlation of r=0.70 (p<0.001).
