A device in the form of a printed chart designed for the qualitative and semi-quantitative assessment of urine analyte (e.g., ketones, glucose, nitrites, leukocytes) concentration/pH by visually comparing urine test strip colour with a standard scale of colour variations that correlate with urine analyte concentration/pH. It is typically used to screen paediatric urine by clinicians in a healthcare facility or by laypersons in the home. This is a single-use device.
