homovanillic acid has been researched along with Sensitivity and Specificity in 44 studies
Homovanillic Acid: A 3-O-methyl ETHER of (3,4-dihydroxyphenyl)acetic acid.
homovanillate : A hydroxy monocarboxylic acid anion which is obtained by deprotonation of the carboxy group of homovanillic acid.
homovanillic acid : A monocarboxylic acid that is the 3-O-methyl ether of (3,4-dihydroxyphenyl)acetic acid. It is a catecholamine metabolite.
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)
