Can an experiment be divided into more than one study, based on where or when the work is performed, or the phase of the experimental work?
Under GLPS, the term "study" refers to an experiment to determine or predict the effects or characteristics of a test substance. EPA considers a study to be composed of all of the necessary elements of research which are performed in order to obtain the reported results. If the elements of research consist of several phases of work which must be taken in the context of each other to get meaningful results, they are all considered to be elements of the same study. An example of this would be where one laboratory treats a test system with a test substance and sends the treated test system to another laboratory for analysis. Another example is if the experiment involves treatment of test systems in several different locations.
