Acute Tubular Necrosis Symptoms & Diagnosis


If you experience any of these symptoms do not assume it is due to acute tubular necrosis. These symptoms may be caused by other, less serious health conditions. If you experience any one of them, see your physician.

  • Change in urine output
  • Dehydration


Your doctor will ask about your symptoms and medical history, and perform a physical exam. Tests may include the following:

  • Blood tests
    • BUN
    • creatinine
    • electrolytes
    • calcium
    • magnesium
    • phosphorus
    • complete blood counts
  • Urine tests (urinalysis, urine sodium, urea, osmolarity)
  • Kidney Biopsy —removal of a sample of kidney tissue for testing (rarely needed)
  • Ultrasound —a test that uses sound waves to examine the kidney
  • Computed tomography (CT scan) —a type of x-ray that uses a computer to make pictures of structures inside the kidney
  • Magnetic resonance imaging (MRI) —a test that uses magnetic waves to make pictures of structures inside the kidney
