The OECD Guidelines for the Testing of Chemicals is a collection of about 100 of the most relevant internationally agreed testing methods used by government, industry and independent laboratories to identify and characterise potential hazards of new and existing chemical substances, chemical preparations and chemical mixtures. They are a set of tools for professionals, used primarily in regulatory safety testing and subsequent chemical and chemical product notification and chemical registration. They can also be used for the selection and ranking of candidate chemicals during the development of new chemicals and products and in toxicology research. This group of tests covers health effects.

Hide / Show Abstract

This method provides information on health hazard likely to arise from exposure to test substance via oral administration. The method is based on the repeated oral administration of the substance of interest during one limited period (one dose level daily during 28 days). This Guideline is intended primarily for use with rodents (rat preferably). At least 10 animals (5 female and 5 male) should be used for each dose level. Three tests groups, at least, should be used. The test compound is administered by gavage or via the diet or drinking water. A limit test may be performed if no effects would be expected at a dose of 1000 mg/kg bw/d. The report of this study will include results from clinical and functional observations, body weight and food/water consumption measurements, hematology and clinical biochemistry; as well as gross necropsy and histopathology.
