Urine tests showed tubular range proteinuria with no microhaematuria. Immunology tests showed elevated serum IgG and hypocomplementaemia (classical pathway activation). Renal biopsy and clinical-pathological correlation were crucial in this case, reinforcing their important role in the final diagnosis of acute kidney injury. ER -
