hydrochloric acid has been researched along with Sensitivity and Specificity in 102 studies
Hydrochloric Acid: A strong corrosive acid that is commonly used as a laboratory reagent. It is formed by dissolving hydrogen chloride in water. GASTRIC ACID is the hydrochloric acid component of GASTRIC JUICE.
hydrogen chloride : A mononuclear parent hydride consisting of covalently bonded hydrogen and chlorine atoms.
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)
