Understanding Proteinuria

Proteinuria, the presence of excess protein in urine, can signify various underlying health issues. It is important to differentiate between benign and pathological causes of proteinuria, as conditions such as urinary tract infections (UTIs) can cause temporary proteinuria due to inflammation. In children, it is critical to assess the type of protein present and the context in which it appears, such as during infections or after strenuous exercise. Clinicians typically employ tests such as urine protein-to-creatinine ratios for accurate assessment, as a simple urine dipstick may not provide definitive results.
