Athletes' Self-Assessment of Urine Color Using Two Color Charts to Determine Urine Concentration. [PDF]
Int J Environ Res Public Health, 2021 Our objective was to determine self-reported accuracy of an athletic population using two different urine color (Uc) charts (8-color vs. 7-color Uc chart). After approval by the Institutional Review Board, members of an athletic population (n = 189, 20 (19–22) year old student- or tactical athletes and coaches, with n = 99 males and n = 90 females ...

Urinary creatinine concentration and urine color as indicators of specimen validity test
Journal of Analytical Science and Technology, 2023 In this study, the concentration of urinary creatinine (Cr) and urine color were analyzed, and a correlation obtained, to objectively verify normal urine samples prior to forensic drug testing. Cr was analyzed via a colorimetric method based on the Jaffé

Urine color as an indicator of urine concentration in pregnant and lactating women. [PDF]
Eur J Nutr, 2017 Urine concentration measured via osmolality (U OSM) and specific gravity (U SG) reflects the adequacy of daily fluid intake, which has important relationships to health in pregnant (PREG) and lactating (LACT) women. Urine color (U COL) may be a practical, surrogate marker for whole-body hydration status.To determine whether U COL was a valid measure of
