vanilmandelic acid has been researched along with Sensitivity and Specificity in 44 studies
Vanilmandelic Acid: A 3-O-methyl ether of 3,4-dihydroxymandelic acid. It is an end-stage metabolite of CATECHOLAMINES; EPINEPHRINE; and NOREPINEPHRINE.
vanillylmandelic acid : An aromatic ether that is the 3-O-methyl ether of 3,4-dihydroxymandelic acid.
Sensitivity and Specificity: Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)
