What is the normal color of a urine sample?

The normal color of a urine sample primarily falls within the range of yellow to pale yellow. This coloration is due to the presence of a pigment called urochrome, which is a breakdown product of hemoglobin. The concentration of urine can also affect its color; for instance, more diluted urine will appear paler, while more concentrated urine may appear deeper in color.

While other colors such as dark brown, red, or completely clear can indicate various health issues or conditions, they are not typical for healthy urine. Dark brown may suggest dehydration or certain diseases affecting the liver, while red could indicate the presence of blood, which is a sign that should be evaluated by a healthcare professional. Clear urine may signify excessive hydration or the potential flushing of essential salts and minerals from the body. Understanding the normal range of urine color is crucial in identifying potential health problems.
