Toxicology
surrogate
Biology; Toxicology
Relatively well studied toxicant whose properties are assumed to apply to an entire chemically and toxicologically related class; for example, benzo(a)pyrene data may be used as toxicologically ...
predictive validity
Biology; Toxicology
Reliability of a measurement expressed in terms of its ability to predict the criterion: an example would be an academic aptitude test that was validated against subsequent academic performance.
plasmapheresis
Biology; Toxicology
Removal of blood from the body and centrifuging it to obtain plasma and packed red blood cells: the blood cells are resuspended in a physiologically compatible solution (usually type-specific fresh ...
subchronic
Biology; Toxicology
Repeated over a short period, usually about 10 % of the life span; an imprecise term used to describe exposures of intermediate duration.
retrospective study
Biology; Toxicology
Research design used to test etiological hypotheses in which inferences about exposure to the putative causal factor(s) are derived from data relating to characteristics of the persons or organisms ...
reconstitution
Biology; Toxicology
Restoration to original form of a substance previously for preservation and storage
risk de minimis
Biology; Toxicology
Risk that is negligible and too small to be of societal concern (usually assumed to be a probability below 10-5 or 10-6). Note 1: This term can also mean ‘virtually safe’. Note 2: In the USA, this is ...
