endpoint determination

Endpoint determination is the process used in laboratory testing to identify the precise moment when a reaction or process has reached completion. For example, in a chemical analysis, it indicates when enough reagent has been added so that the reaction is fully finished, ensuring accurate measurements. This is often done by observing a change—such as a color shift or a signal reaching a certain value—that signals the endpoint. Accurate endpoint determination is crucial because it ensures the results of the test are reliable and reproducible.
