Conducting a diagnostic test for indoor air quality is primarily aimed at assessing potential indoor air pollutants. This process involves measuring and analyzing various factors that can contribute to poor air quality within a building, such as the presence of volatile organic compounds (VOCs), carbon dioxide levels, humidity, and other harmful substances. Understanding the concentration and sources of these pollutants is essential in identifying health risks for occupants and developing strategies to improve air quality.

The emphasis on indoor air pollutants is crucial since these can significantly impact occupant health and comfort, as well as overall building performance. By identifying and addressing these issues, effective solutions can be implemented to enhance indoor environments, thereby supporting occupants' well-being and health. This focus on air quality distinguishes it from other aspects such as energy bills or structural integrity, which, while important, do not directly relate to the diagnostic focus on air pollutants.
