Human fluorescent profile of urine as a simple tool of mining in data from autofluorescence spectroscopy

Abstract Human urine is one of most accessible body fluids and its collection does not burden patients. Wide spectrum of compounds present in urine with a close relation to metabolism determines a large diagnostic potential. Presented work is focused on information extraction from autofluorescent data analysis of urine. Simple modified synchronous autofluorescent spectrum of urine sample – human fluorescent profile of urine (HFPU) seems to be powerful in mining distinct characters and could be meaningful tool for classification of patients into subgroups according to specific fluorescent characteristics without exact knowledge of urine composition. This could be beneficial in broad range of applications on urine autofluorescence. Offered concept of autofluorescent fingerprints evaluation was tested on 119 urine samples. In this study was found that patients with hypertension have lower intensity of fluorescence at the wavelength range 380–450 nm compare to healthy.
