Developmental toxicity is any developmental malformation that is caused by the toxicity of a chemical or pathogen. It is the structural or functional alteration, reversible or irreversible, which interferes with homeostasis , normal growth , differentiation , development or behavior.

Six tests are: acute toxicity, chronic toxicity, developmental toxicity/reproductive toxicity, mutagenicity, ecotoxicity and environmental fate. Using SIDS and detailed exposure data OECD's High Production Volume Chemicals Programme conducted initial risk assessments to screen and to identify any need for further work.
In drug development, preclinical development (also termed preclinical studies or nonclinical studies) is a stage of research that begins before clinical trials (testing in humans) and during which important feasibility, iterative testing and drug safety data are collected, typically in laboratory animals.
U.S. Army Public Health Center Toxicology Lab technician assessing samples. Toxicology testing, also known as safety assessment, or toxicity testing, is the process of determining the degree to which a substance of interest negatively impacts the normal biological functions of an organism, given a certain exposure duration, route of exposure, and substance concentration.
This test is the best protocol for testing samples of unknown toxicity, a high level of toxicity, or when the test results are required to provide the highest confidence and precision. This test consists of two controls and eight sample dilutions in duplicate. [14] Acute Toxicity 100% Test is a procedure that tests the sample at 100% sample ...
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 ...
Feedback from this pilot and continuous efforts to more closely align this implementation with the SDTM for human clinical trials led to development of SEND 2.3, but without widespread adoption. In 2006, with renewed FDA interest, the industry met to revive SEND and work on a version that, with FDA backing, would cover regulatory submission as ...
