Abstract
The disclosure relates to a method for providing original data that can be used for subsequently determining the function of an organ of a living organism or for subsequently diagnosing a disease or a severity of a disease of an organ of a living organism. This method is characterized by several steps, one of which is administering a marker substance to a living organism by inhalation, wherein the marker substance has a vapor pressure above 0.01 mmHg at 37° C. In other method steps, the concentration of this marker substance in exhaled air is determined at at least two different time points. Then, a difference in marker substance concentration is calculated.
