Answer

Blood studies and urinalysis, along with renal ultrasound findings, are particularly helpful in identifying the cause of acute tubular necrosis (ATN). Findings on some tests will vary depending on the cause of ATN. Careful monitoring of the fluid balance, ongoing medication details, and daily physical examinations should all be considered together with laboratory tests.
