Toxicology testing is commonly conducted during preclinical development for a substance intended for human exposure. Stages of in silico, in vitro and in vivo research are conducted to determine safe exposure doses in model organisms. If necessary, the next phase of research involves human toxicology testing during a first-in-man study.
A drug test (also often toxicology screen or tox screen) is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/saliva—to determine the presence or absence of specified parent drugs or their metabolites.

While toxicology tests are performed on all overdose deaths, showing which drugs were present in the person’s system and at what quantity, an autopsy provides the most comprehensive and accurate ...
In vitro toxicity testing is the scientific analysis of the toxic effects of chemical substances on cultured bacteria or mammalian cells. [1] In vitro (literally 'in glass') testing methods are employed primarily to identify potentially hazardous chemicals and/or to confirm the lack of certain toxic properties in the early stages of the development of potentially useful new substances such as ...
Toxicology tests showed that on the morning of Feb. 1, 2023, Escobedo had a blood-alcohol level of nearly 0.3, about four times the level of .08 at which it is illegal to drive in Florida, a PBSO ...
The classic experimental tool of toxicology is testing on non-human animals. [12] Examples of model organisms are Galleria mellonella , [ 25 ] which can replace small mammals, Zebrafish ( Danio rerio ), which allow for the study of toxicology in a lower order vertebrate in vivo [ 26 ] [ 27 ] and Caenorhabditis elegans . [ 28 ]
