What Is Acute Renal Failure?
4. Diagnosis
When a patient’s signs indicate the possibility of acute renal failure, tests are run to confirm a diagnosis. The physician may take measurements of how much urine is eliminated over a 24-hour period and analyze the urine for irregularities.
Blood tests are often used to detect urea and creatinine levels, both of which are waste products that are found in the blood. High levels of these substances are indicative of acute renal failure. Occasionally, a biopsy is performed to determine whether any kidney damage or disease is present.
