A 3D color model reports urine color similarly to a printed color chart with similar accuracy to determine a low vs. high urine concentration.

ABSTRACT:

Background

Urine color (Uc) assessment is impacted by container, volume, and light conditions, potentially influencing Uc scoring. This study aimed to evaluate a 3D Uc model vs. Printed Uc chart's accuracy for identifying a low vs. high urine concentration in the morning and afternoon.

Results

Participants (n = 73, 12% female, age: ~ 27 years) collected all urine voids for two consecutive days (32 h total), resulting in two partially concurrent 24-h urine collections that were compared with a morning and afternoon assessment. Median and [interquartile range] Uc differed between the Printed chart and 3D Uc model in the morning (2.0 [1.5-3.0] vs. 2.0 [2.0-4.0], p < 0.001), but not in the afternoon (2.0 [1.0 - 3.0] vs. 2.0 [1.0 - 3.0], p = 0.07). The models
