Blood Tests: To evaluate kidney function and detect underlying conditions.
Imaging Studies: Ultrasound or other imaging techniques to visualize kidney structure and detect abnormalities.
Kidney Biopsy: In some cases, a biopsy may be needed to diagnose specific kidney disorders.

Early intervention and regular monitoring are key to managing kidney disease in children and improving outcomes.
