A child is three years old, with 1+ occult blood in urine, 25 cells/μL, red cells

Patient's question:

Detailed medical condition and consultation purpose: Urinalysis occult blood +1, other problems are normal
Duration and persistence of this illness: 3 months, sometimes detected, sometimes not
Current general condition: No obvious discomfort
Medical history: Frequent colds causing upper respiratory infection
Previous diagnoses, treatment history, and outcomes: Occult blood + disappeared for a period without medication
Other: Asking how to treat it

Doctor's answer:

Hello: Urine occult blood can only indicate the presence of red blood cell components in the urine. In normal human bodies, red blood cells are constantly broken down, and their components are excreted through the urine. Therefore, it is normal for the urine of healthy individuals to show positive occult blood. Weakly positive or positive results have no significant clinical value.
