Blood in the urine (hematuria) is not common in children and may be a
sign of an infection, a kidney problem, or an injury. The blood may either be
seen with the naked eye (gross hematuria) or seen only when the urine sample is
examined under a microscope.
It is common for newborns to pass some pink urine in the first 3 days of life. This may be from crystals in the urine. Parents will notice a pink color to the urine in the diaper.
Note: If no other urinary symptoms are present, a slight change in
urine color could be from eating beets or other red foods.
