It is necessary to quickly establish if azotemia is acute or chronic and whether it is due to prerenal, intrarenal, or postrenal causes. This is vital in initiating treatment and in preventing progression. Clinical evaluation requires a thorough history, physical examination, and specific laboratory tests (including serologies, urinalysis, and, if indicated, radiologic studies and kidney biopsy; see Workup).
