Urine color (COL)

Urine color may be indicative of kidney disorders. Evaluate the color of your urine by viewing the sample put in a clear container against a white background with the aid of a good light source.

The urine color of a healthy person ranges from pale straw yellow to amber yellow. Urine color depends on the substances formed from pigments found in blood (urohematin, hematoporphyrin, urochromes, etc.).

Urine may have an unusual color. The shade of your urine depends on the amount of water you drink. The more you drink, the lighter your urine. The less you drink, the darker and more concentrated your urine. Urine color may be changed by vitamins, medications or some foods (beets, carrots).

Generally, changes in urine color are temporary and have no serious consequences. However, sometimes such changes may be caused by an infection or another severe disease.

The most frequent changes in urine color than are not caused by a disease:

  • Pink or red: beetroot, blackberries, rhubarb; phenolphthalein, propofol, rifampicin, laxatives containing senna
  • Brown: fava beans, rhubarb; levodopa, metronidazole, nitrofurantoin, some anti-malarial agents, methyldopa, laxatives containing cascara or senna
