End point determination

End point determination is the process used in laboratory testing to identify the exact moment when a reaction or process has reached its completion. In practice, this involves monitoring a test, such as a chemical reaction, until a specific change indicates that the desired measurement or result is achieved. For example, in titrations, an indicator shows when enough reactant has been added. Accurate end point determination ensures precise and reliable test results, which are essential for proper diagnosis or analysis. Essentially, it's about knowing precisely when to stop the process to obtain the best possible data.
