The National Library of Medicine (NLM), on the campus of the National Institutes of Health in Bethesda, Maryland, is the world's largest medical library. The Library collects materials and provides information and research services in all areas of biomedicine and health care.
1. Quotient of the change in the indication and the corresponding change in the value of the quantity being measured.
2. Slope of the calibration curve. If the curve is in fact a ‘curve’, rather than a straight line, then of course sensitivity will be a function of analyte concentration or amount. If sensitivity is to be a unique performance characteristic, it must depend only on the chemical measurement process, not upon scale factors.
Industry:Biology; Chemistry
1. Ratio of the risk of disease or death among the exposed to the risk among the unexposed.
2. Ratio of the cumulative incidence rate in the exposed to the cumulative incidence rate in the unexposed.

2. Ratio of the cumulative incidence rate in the exposed to the cumulative incidence rate in the unexposed.
Industry:Biology; Chemistry
1. Relating to the body as a whole.
2. Occurring at a site in the body remote from the point of contact with a substance.
Industry:Biology; Chemistry
1. Study designed to establish the pattern of pesticide residue intake by a person consuming a defined diet.
2. Study undertaken to show the range and amount of various foodstuffs in the typical diet or to estimate the total amount of a specific substance in a typical diet.
Industry:Biology; Chemistry
1. Substance material on which an enzyme acts.
2. Surface on which an organism grows or to which is attached.
Industry:Biology; Chemistry
Ability of a substance to remain in a particular environment in an unchanged form.
Industry:Biology; Chemistry
Ability to withstand the effect of various factors including potentially toxic substances.
Industry:Biology; Chemistry
Able to cause injury to living organisms as a result of physicochemical interaction.
Industry:Biology; Chemistry
Absolute difference between two rates.
Note 1: For example, the difference in incidence rate between a population group exposed to a causal factor and a population group not exposed to the factor.
Note 2: In comparisons of exposed and unexposed groups, the term ‘excess rate’ may be used as a synonym for rate difference.
