Abstract

<p>There are many fluorescent substances in urine and urinary sediments. We have confirmed the fluorescence of xanthine and 2,8-dihydroxyadenine (2,8-DHA) crystals, which can be formed by purine catabolism, and tosufloxacin crystals that are derived from the tosufloxacin tosilate antimicrobial drug. A fluorescent pale blue color is obtained from salts/crystals in casts, human hair, nails, and stratified squamous keratinized epithelia. Commercially available uric acid is a colorless and thin crystal and has a faint pale blue fluorescence. Uric acid crystals obtained from the urine of students and kept in a refrigerator were found to be very pure (over 98% purity) by infrared absorption spectroscopy. They also showed different colors, namely, yellow brown, and red brown under visible light and pale blue and yellow green under fluorescent light. Each color may be included owing to the fluorescence of uric acid and the incorporation of urinary colored pigments.</p>
