Could a child's positive occult blood (1+) indicate kidney disease?

Generally, a child's urine occult blood 1+ may be caused by kidney disease, or it could result from dietary factors or viral infections. The specific analysis is as follows:

I. Yes (indicating possible kidney disease)

1. Glomerulonephritis

Glomerulonephritis is one of the common kidney diseases, which can present with abnormal urine, proteinuria, hematuria, hypertension, and other symptoms. If a child shows occult blood 1+ along with these symptoms, glomerulonephritis should be considered.

2. IgA Nephropathy

IgA nephropathy is an immune-related disorder, mainly characterized by proteinuria, hematuria, hypertension, and renal insufficiency. Occult blood 1+ can also be one of its manifestations, suggesting the possibility of IgA nephropathy in children.

II. No (not necessarily kidney disease)

1. Dietary Factors

Poor nutrition or excessive preference for certain foods may increase the burden on the kidneys, leading to abnormal urine, including occult blood 1+.

2. Viral Infections

Certain viral infections may cause symptoms such as fever, headache, and fatigue, and can also lead to urinary abnormalities. Occult blood 1+ might be one of these infection-related symptoms.

When occult blood 1+ appears along with other symptoms, potential kidney problems should be taken seriously. Help the child maintain strict dietary control, avoiding spicy, stimulating, and high-calorie foods. Additionally, schedule regular health check-ups for the child to detect and treat any conditions early.
