Urine self-testing kit. General practitioner (GP) using a kit for testing urine for signs of diabetes, kidney problems and urinary tract infections. The dipstick is immersed in urine and compared to the colour chart. From bottom to top, the ten coloured pads are showing the results of tests for glucose, bilirubin, ketones, specific gravity (density), blood, pH levels, proteins, urobilinogen, nitrites, and leucocytes (white blood cells). High levels of glucose and ketones in the urine are symptoms of diabetes. High concentrations of blood cells and other substances may indicate infection or kidney problems. This is the DUS 10 Home Test system. Photographed in Edinburgh, Scotland.
