Visualization of the composition of the urinary fluorescent metabolome. Why is it important to consider initial urine concentration?

Abstract

Abstract Urine is a highly complex fluorescent system, the fluorescence of which can be affected by many factors, including the often-ignored initial urine concentration in comprehensive fluorescent urine analysis. In this study, a total urine fluorescent metabolome profile (uTFMP) was created as a three-dimensional fluorescence profile of serial synchronous spectra of urine diluted by geometric progression. uTFMP was generated using software designed for this purpose after recalculating the 3D data concerning the initial urine concentration. It can be presented as a contour map (top view) or as a more illustrative and straightforward simple curve, thus usable in various medicinal applications.
